Zarlink Semiconductor Inc.
Description
The ZL50118/19/20 family of CESoP processors are highly functional TDM to Packet bridging devices. The
ZL50118/19/20 provides both structured and unstructured circuit emulation services (CES) for T1 and E1 streams
across a packet network based on MPLS, IP or Ethernet. The ZL50120 also supports unstructured J2, T3, E3 and
STS-1.
The circuit emulation features in the ZL50118/19/20 family comply with the ITU Recommendation Y.1413, as well
as the emerging CES standards from the Metro Ethernet Forum (MEF) and MPLS and Frame Relay Alliance
(MFA). The ZL50118/19/20 also complies with the standards currently being developed within the IETF's PWE3
working group, listed below.
Structure-Agnostic TDM over Packet (SAToP) - draft-ietf-pwe3-satop
Structure-aware TDM Circuit Emulation Service over Packet Switched Network (CESoPSN) -
draft-ietf-pwe3-cesopsn
The ZL50118/19/20 provides a customer side 100 Mbps MII port to aggregate data traffic with voice traffic to the
provider side 1000 Mbps GMII/TBI port, thereby eliminating the need for an external Ethernet switch.
The ZL50118/19/20 incorporates a range of powerful clock recovery mechanisms for each TDM stream, allowing
the frequency of the source clock to be faithfully generated at the destination, enabling greater system performance
and quality. Timing is carried using RTP or similar protocols, and both adaptive and differential clock recovery
schemes are included, allowing the customer to choose the correct scheme for the application. An externally
supplied clock may also be used to drive the TDM interface of the ZL50118/19/20.
The ZL50118/19/20 incur very low latency for the data flow, thereby increasing QoS when carrying voice services
across the Packet Switched Network. Voice, when carried using CESoP, which typically has latencies of less than
10 ms, does not require expensive processing such as compression and echo cancellation.
The ZL50118/19/20 are cost effective devices aimed at the low density applications such as customer premise
routers, IADs, ePON termination and Broadband DLCs. For network systems, the ZL50118/19/20 is fully
compatible and interoperable with the ZL50110/11/14 family.
The ZL50118/19/20 is capable of assembling user-defined packets of TDM traffic from the TDM interface and
transmitting them out the packet interfaces using a variety of protocols. The ZL50118/19/20 supports a range of
different packet switched networks, including Ethernet VLANs, IP (both versions 4 and 6) and MPLS. The devices
also supports four different classes of service on packet egress, allowing priority treatment of TDM-based traffic.
This can be used to help minimize latency variation in the TDM data.
Packets received from the packet interfaces are parsed to determine the egress destination, and are appropriately
queued to the TDM interface, they can also be forwarded to the host interface, or back toward the packet interface.
Packets queued to the TDM interface can be re-ordered based on sequence number, and lost packets filled in to
maintain timing integrity.
The ZL50118/19/20 includes on-chip memory sufficient for all applications, thereby reducing system costs, board
area, power, and design complexity.
A comprehensive evaluation system is available upon request from your local Zarlink representative or distributor.
This system includes the CESoP processor, various TDM interfaces and a fully featured evaluation software GUI
that will run on a Windows PC.

2.1 TDM Interface
All TDM Interface signals are 5 V tolerant.
All TDM Interface outputs are high impedance while System Reset is LOW.
All TDM Interface inputs (including data, clock and frame pulse) have internal pull-down resistors so they can be
safely left unconnected if not used.
2.1.1 TDM stream connections
There are three interfaces possible among the ZL50118/19/20.
The ZL50120 supports four TDM ports [3:0] at 2 Mbps, or one TDM port [0] at 8 Mbps or one unstructured TDM port
[0] for J2/E3/T3/STS-1.
The ZL50119 supports two TDM ports [1:0] at 2 Mbps, or one TDM port [0] at 8 Mbps (up to 64 DS0).

2.3 Packet Interfaces
For the ZL50118/19/20 variants the packet interface is capable of either 2 MII interfaces, or 1 MII and 1 GMII
interfaces, or 1 MII and 1 TBI (1000 Mbps) interfaces. The TBI interface is a PCS interface supported by an
integrated 1000BASE-X PCS module.
Data for all three types of packet switching is based on Specification IEEE Std. 802.3 - 2000. Only Port 0 has the
1000 Mbps capability necessary for the GMII/TBI interface.
Table 6 maps the signal pins used in the MII interface to those used in the GMII and TBI interface. Table 7 shows all
the pins and their related package ball, but is based on the GMII/MII configuration.
All Packet Interface signals are 5V tolerant, and all outputs are high impedance while System Reset is LOW.
Note: Mn can be either M0 or M1 for ZL50118/19/20 variants.

3.0 Typical Applications
3.1 Leased Line Provision
Circuit emulation is typically used to support the provision of leased line services to customers using legacy TDM
equipment. For example, Figure 4 shows a leased line TDM service being carried across a packet network. The
advantages are that a carrier can upgrade to a packet switched network, whilst still maintaining their existing TDM
business.
The ZL50118/19/20 is capable of handling circuit emulation of both structured T1, E1, and J2 links (e.g., for support
of fractional circuits) and unstructured (or clear channel) T1, E1, J2, T3 and E3 links. The device handles the
data-plane requirements of the provider edge inter-working function (with the exception of the physical interfaces
and line interface units). Control plane functions are forwarded to the host processor controlling the ZL50118/19/20
device.
The ZL50118/19/20 provides a per-stream clock recovery function to reproduce the TDM service frequency at the
egress of the packet network. This is required otherwise the queue at the egress of the packet network will either fill
up or empty, depending on whether the regenerated clock is slower or faster than the original.

3.2 Remote Concentrator Unit
The remote concentrator application, shown in Figure 5, consists of a remote concentrators connected to the
Central Office (CO) by a dedicated fiber link running Gigabit Ethernet (GE) or Ethernet over SONET (EoS) rather
than by NxT1/E1 or DS3/E3. The remote concentrators provide both TDM service and native Ethernet service to
the Multi-Tenet Unit or Multi-Dwelling Unit (MTU/MDU).
The ZL50118/19/20 is used to emulate TDM circuits over Ethernet by establishing CESoP connections between the
remote concentrator and the CO. The native IP or Ethernet traffic is multiplexed with the CESoP traffic inside the
remote concentrator and sent across the same GE connection to the CO. At the CO the native IP or Ethernet traffic
is split from the CESoP connections at sent towards the packet network. Multiple T1/E1 CESoP connections from
several remote concentrators are aggregated in the CO using a larger ZL50118/19/20 variant, converted back to
TDM circuits, and connected to the PSTN through a higher bandwidth TDM circuit such as OC-3 or STM-1.
The use of CESoP here allows the convergence of voice and data on a single access network based on Ethernet.
This convergence on Ethernet, a packet technology, rather than SONET/SDH, a switched circuit technology,
provides cost and operational savings.

3.3 FTTP
The Fiber to the Premise (FTTP) application, shown in Figure 6, consists of an Ethernet Passive Optical Network
(EPON) deployed in the Wide Area Network (WAN). The Optical Network Units (ONU) sit at the curb while the
Optical Line Terminals (OLT) are located at the Central Office (CO). The ONUs are traditionally equipped with
Ethernet interfaces to provide video and data service to the customer premise.
The ONU includes a ZL50118/19/20 which enables the box to provide T1/E1 service to the customer. The
ZL50118/19/20 is used to establish CESoP connections between the ONU and the OLT to transparently carry TDM
circuits across the EPON. The ONU would use a smaller variant of the ZL50118/19/20 and the OLT would use a
larger variant to aggregate CESoP traffic from many ONUs and connect them at the CO to the PSTN. The native IP
or Ethernet traffic from the ONU would be split off at the OLT and connected to the packet network.

3.4 Wireless - WiFi or WiMAX
The wireless application, shown in Figure 7, may either be in the form of WiMAX for broadband access or Wi-Fi for
smaller-scale Loans. Both technologies carry Ethernet over radio links between sites or pieces of equipment.
An application for CESoP technology over a WiMAX network is to enable the service provider to sell T1/E1 service
in addition to video and data services that are natively carried across the WiMAX connection. A ZL50118/19/20 is
used at the customer premise to packetize the T1/E1, fractional T1/E1 or TDM circuit into Ethernet packets, which
are transported back to the Central Office (CO). At the CO the TDM circuit is re-assembled from the Ethernet
packets and send to the PSTN. The CESoP traffic is converged onto the same WiMAX connection as the native
Ethernet traffic for video and data.
An application for CESoP technology over a Wi-Fi network is to enable a distributed PBX system in either a single
building or between buildings in a campus environment. In this application the T1/E1 connection from a PBX is
connected using a CESoP to another PBX. A wireless site-to-site CESoP connection between buildings in a
campus would allow for deployment savings against having to run dedicated copper cables between buildings.

3.5 Digital Loop Carrier
The Broadband Digital Loop Carrier (BBDLC) application, shown in Figure 8, consists of a BBDLC connected to the
Central Office (CO) by a dedicated fiber link running Gigabit Ethernet (GE) rather than by NxT1/E1 or DS3/E3.
The ZL50118/19/20 is used to emulate TDM circuits over Ethernet by establishing CESoP connections between the
BBDLC and the CO. At the CO the native IP or Ethernet traffic is split from the CESoP connections at sent towards
the packet network. Multiple T1/E1 CESoP connections from several BBDLC are aggregated in the CO using a
larger ZL50118/19/20 variant, converted back to TDM circuits, and connected to a class 5 switch destined towards
the PSTN.
In this configuration T3/E3 services can also be provided. Using CESoP allows voice and data traffic to be
converged onto a single link.

3.6 Integrated Access Device
The Integrated Access Device (IAD) application consists of an IAD located at the curb or customer premise with an
Ethernet connection to an TDM aggregation box sitting in the access area of the network.
The ZL50118/19/20 in the IAD modem packetizes the T1/E1 or fractional T1/E1 TDM circuit into Ethernet CESoP
packets. The CESoP traffic is multiplexed with the native Ethernet data traffic from the IAD’s Ethernet ports onto the
Ethernet link to the aggregation equipment. The aggregator will split off the native Ethernet traffic from multiple
IADs and send the traffic on to packet network. The aggregator will contain a larger ZL50118/19/20 that will
terminate multiple CESoP connections from multiple IADs and send the TDM circuits to the PSTN, perhaps over a
higher bandwidth TDM pipe such as DS3.
The use of CESoP in this application allows the IAD to support both native Ethernet service as well as T1/E1
service in the same box, while converging both types of traffic onto a single Ethernet connection back towards the
provider.

4.0 Functional Description
The ZL50118/19/20 family provides the data-plane processing to enable constant bit rate TDM services to be
carried over a packet switched network, such as an Ethernet, IP or MPLS network. The device segments the TDM
data into user-defined packets, and passes it transparently over the packet network to be reconstructed at the far
end. This has a number of applications, including emulation of TDM circuits and packet backplanes for TDM-based
equipment.

4.1 Block Diagram
A diagram of the ZL50118/19/20 device is given in Figure 11, which shows the major data flows between functional
components.

4.2 Data and Control Flows
There are numerous combinations that can be implemented to pass data through the ZL50118/19/20 device
depending on the application requirements. The Task Manager can be considered the central pivot, through which
all flows must operate. The Task Manager acts as a “router” in the centre of the chip, directing packets to the
appropriate blocks for further processing. The task message contains a pointer to the relevant data, instructions as
to what to do with the data, and ancillary information about the packet. Effectively this means the flow of data
through the device can be programmed, by setting the task message contents appropriately.

Each of the 11 data flows uses the Task Manager to route packet information to the next block or interface for
onward transmission. The flow is determined by the Type field in the Task Message (see ZL50118/19/20
Programmers Model).
4.3 TDM Interface
The ZL50118/19/20 family offers the following types of TDM service across the packet network:
Unstructured services are fully asynchronous, and include full support for clock recovery on a per stream basis.
Both adaptive and differential clock recovery mechanisms can be used.
Structured services are synchronous, with all streams driven by a common clock and frame reference. These
services can be offered in two ways:
Synchronous master mode - the ZL50118/19/20 provides a common clock and frame pulse to all streams,
which may be locked to an incoming clock or frame reference
Synchronous slave mode - the ZL50118/19/20 accepts a common external clock and frame pulse to be
used by all streams
In either structured mode, N x 64 Kbps trunking is supported as detailed in “Payload Order” on page 50.
4.3.1 TDM Interface Block
The TDM Interface contains two basic types of interface: unstructured clock and data, for interfacing directly to a
line interface unit; or structured, framed data, for interfacing to a framer or TDM backplane.
Unstructured data is treated asynchronously, with every stream using its own clock. Clock recovery is provided on
each output stream, to reproduce the TDM service frequency at the egress of the packet network. Structured data is
treated synchronously, i.e. all data streams are timed by the same clock and frame references. These can either be
supplied from an external source (slave mode) or generated internally using the on-chip stratum 3/4/4E PLL
(master mode).

4.3.2 Structured TDM Port Data Formats
The ZL50118/19/20 is programmable such that the frame/clock polarity and clock alignment can be set to any
desired combination. Table 21 shows a brief summary of four different TDM formats; ST-BUS, H.110, H-MVIP, and
Generic (synchronous mode only), for more information see the relevant specifications shown. There are many
additional formats for TDM transmission not depicted in Table 21, but the flexibility of the port will cover almost any
scenario. The overall data format is set for the entire TDM Interface device, rather than on a per stream basis. It is
possible to control the polarity of the master clock and frame pulse outputs, independent of the chosen data format
(used when operating in synchronous master mode).

4.3.3 TDM Clock Structure
The TDM interface can operate in two modes, synchronous for structured TDM data, and asynchronous for
unstructured TDM data. The ZL50118/19/20 is capable of providing the TDM clock for either of the modes, but clock
recovery is only possible in asynchronous mode, where the timing for each stream is controlled independently.
4.3.3.1 Synchronous TDM Clock Generation
In synchronous mode all 4 streams will be driven by a common clock source. When the ZL50118/19/20 is acting as
a master device, the source can either be the internal DPLL or an external PLL. In both cases, the primary and
secondary reference clocks are taken from either two TDM input clocks, or two external clock sources driven to the
chip. The input clocks are then divided down where necessary and sent either to the internal DPLL or to the output
pins for connection to an external DPLL. The DPLL then provides the common clock and frame pulse required to
drive the TDM streams. See “DPLL Specification” on page 58 for further details.
Figure 12 - Synchronous TDM Clock Generation
When the ZL50118/19/20 is acting as a slave device, the common clock and frame pulse signals are taken from an
external device providing the TDM master function.
4.3.3.2 Asynchronous TDM Clock Generation
Each stream uses a separate internal DCO to provide an asynchronous TDM clock output. The DCO can be
controlled to recover the clock from the original TDM source depending on the timing algorithm used.
4.4 Payload Assembly
Data traffic received on the TDM Interface is sampled in the TDM Interface block, and synchronized to the internal
clock. It is then forwarded to the payload assembly process. The ZL50118/19/20 Payload Assembler can handle up
to 128 active packet streams or “contexts” simultaneously. Each context generates a single stream of packets
identified by a label in the packet header known as the "context ID". Packet payloads are assembled in the format
shown in Figure 13 on page 49 in structured operation. This meets the requirements of the CESoPSN standard
under development in the IETF. Alternatively, packet payloads are assembled in the format shown in Figure 15 on
page 50. This format meets the requirements of the SAToP standard under development in the IETF.
When the payload has been assembled it is written into the centrally managed memory, and a task message is
passed to the Task Manager.

4.4.1 Structured Payload Operation
In structured mode a context may contain any number of 64 kbps channels. These channels need not be
contiguous and they may be selected from any input stream.
Channels may be added or deleted dynamically from a context. This feature can be used to optimize bandwidth
utilisation. Modifications to the context are synchronised with the start of a new packet.
The fixed header at the start of each packet is added by the Packet Transmit block. This consists of up to 64 bytes,
containing the Ethernet header, any upper layer protocol headers, and the two byte context descriptor field (see
section below). The header is entirely user programmable, enabling the use of any protocol.
The payload header and size must be chosen so that the overall packet size is not less than 64 bytes, the Ethernet
standard minimum packet size. Where this is likely to be the case, the header or data must be padded (as shown in
Figure 13 and Figure 15) to ensure the packet is large enough. This padding is added by the ZL50118/19/20 for
most applications.
Figure 13 - ZL50118/19/20 Packet Format - Structured Mode
In applications where large payloads are being used, the payload size must be chosen such that the overall packet
size does not exceed the maximum Ethernet packet size of 1518 bytes (1522 bytes with VLAN tags). Figure 13
shows the packet format for structured TDM data, where the payload is split into frames, and each frame
concatenated to form the packet.

4.4.1.1 Payload Order
Packets are assembled sequentially, with each channel placed into the packet as it arrives at the TDM
Interface. A fixed order of channels is maintained (see Figure 14), with channel 0 placed before channel 1,
which is placed before channel 2. It is this order that allows the packet to be correctly disassembled at the far
end. A context must contain only unique channel numbers. As such a context that contains the same channel
from different streams, for example channel 1 from stream 2 and channel 1 from stream 3, would not be
permitted.
Figure 14 - Channel Order for Packet Formation
Each packet contains one or more frames of TDM data, in sequential order. This groups the selected channels
for the first frame, followed by the same set of channels for the subsequent frame, and so on.
4.4.2 Unstructured Payload Operation
In unstructured mode, the payload is not split by defined frames or timeslots, so the packet consists of a continuous
stream of data. Each packet consists of a number of octets, as shown in Figure 15. The number of octets in a
packet need not be an integer number of frames. A typical value for N may be 192, as defined in the IETF PWE3
standard."
For example, consider mapping the unstructured data of a 25 timeslot DS0 stream. The data for each T1 frame
would normally consist of 193 bits, 192 data bits and 1 framing bit. If the payload consists of 24 octets it will be 1 bit
short of a complete frames worth of data, if the payload consists of 25 octets it will be 7 bits over a complete frames
worth of data. NOTE: No alignment of the octets with the T1 framing structure can be assumed.

4.5 Protocol Engine
In general, the next processing block for TDM packets is the Protocol Engine. This handles the data-plane
requirements of the main higher level protocols (layers 4 and 5) expected to be used in typical applications of the
ZL50118/19/20 family: UDP, RTP, L2TP, CESoPSN, SAToP and CDP. The Protocol Engine can add a header to the
datagram containing up to 24 bytes. This header is largely static information, and is programmed directly by the
CPU. It may contain a number of dynamic fields, including a length field, checksum, sequence number and a
timestamp. The location, and in some cases the length of these fields is also programmable, allowing the various
protocols to be placed at variable locations within the header.
4.6 Packet Transmission
Packets ready for transmission are queued to the switch fabric interface by the Queue Manager. Four classes of
service are provided, allowing some packet streams to be prioritized over others. On transmission, the Packet
Transmit block appends a programmable header, which has been set up in advance by the control processor.
Typically this contains the data-link and network layer headers (layers 2 and 3), such as Ethernet, IP (versions 4
and 6) and MPLS.
4.7 Packet Reception
Incoming data traffic on the packet interface is received by the MACs. The well-formed packets are forwarded to a
packet classifier to determine the destination. When a packet is successfully classified the destination can be the
TDM interface, the LAN interface or the host interface. TDM traffic is then further classified to determine the context
it is intended for.
Each TDM interface context has an individual queue, and the TDM re-formatting process re-creates the TDM
streams from the incoming packet streams. This queue is used as a jitter buffer, to absorb variation in packet delay
across the network. The size of the jitter buffer can be programmed in units of TDM frames (i.e., steps of 125 µs).
There is also a queue to the host interface, allowing a traffic flow to the host CPU for processing. The host’s DMA
controller can be used to retrieve packet data and write it out into the CPU’s own memory.
4.8 TDM Formatter
At the receiving end of the packet network, the original TDM data must be re-constructed from the packets
received. This is known as re-formatting, and follows the reverse process from the Payload Assembler. The TDM
Formatter plays out the packets in the correct sequence, directing each octet to the selected timeslot on the output
TDM interface.
When lost or late packets are detected, the TDM Formatter plays out underrun data for the same number of TDM
frames as were included in the missing packet. Underrun data can either be the last value played out on that
timeslot, or a pre-programmed value (e.g., 0xFF). If the packet subsequently turns up it is discarded. In this way, the
end-to-end latency through the system is maintained at a constant value.
4.9 Ethernet Traffic Aggregation
The ZL50118/19/20 allows native Ethernet traffic received on the customer side Fast Ethernet port to be
aggregated with the CESoP traffic from the TDM interface to the provider side Gigabit Ethernet port. Likewise,
traffic from the provider side Gigabit Ethernet port may be split between CESoP traffic destined towards the TDM
interface and native Ethernet traffic destined towards the customer side Fast Ethernet port. This functionality is
achieved by correctly programming the task manager and packet classifiers for flow 11.
From the provider side Gigabit Ethernet port to the customer side TDM and Fast Ethernet interfaces there is
sufficient internal bandwidth to avoid any prioritization issues. From the customer side TDM and Fast Ethernet
interfaces towards the Gigabit Ethernet ports the TDM CESoP traffic may be sent to a higher priority output queue
(there are four output queues total) than the native Fast Ethernet traffic. In this way the access to the provider side
Gigabit Ethernet port is prioritized for TDM traffic over native Ethernet traffic.

5.0 Clock Recovery
One of the main issues with circuit emulation is that the clock used to drive the TDM link is not necessarily linked
into the central office reference clock, and hence may be any value within the tolerance defined for that service.
The reverse link may also be independently timed, and operating at a slightly different frequency. In the
plesiochronous digital hierarchy the difference in clock frequencies between TDM links is compensated for using bit
stuffing techniques, allowing the clock to be accurately regenerated at the remote end of the carrier network.
With a packet network, that connection between the ingress and egress frequency is broken, since packets are
discontinuous in time. From Figure 4, the TDM service frequency fservice at the customer premises must be exactly
reproduced at the egress of the packet network. The consequence of a long-term mismatch in frequency is that the
queue at the egress of the packet network will either fill up or empty, depending on whether the regenerated clock is
slower or faster than the original. This will cause loss of data and degradation of the service.
The ZL50118/19/20 provides a per-stream clock recovery function to reproduce the TDM service frequency at the
egress of the packet network. There are two schemes are employed, depending on the availability of a common
reference clock at each provider edge unit, within the ZL50118/19/20 - differential and adaptive. The clock recovery
itself is performed by software in the external processor, with support from on-chip hardware to gather the required
statistics.
5.1 Differential Clock Recovery
For applications where the wander characteristics of the recovered clock are very important, such as when the
emulated circuit must be connected into the plesiochronous digital hierarchy (PDH), the ZL50118/19/20 also offers
a differential clock recovery technique. This relies on having a common reference clock available at each provider
edge point. Figure 16 illustrates this concept with a common Primary Reference Source (PRS) clock being present
at both the source and destination equipment.
In a differential technique, the timing of the TDM service clock is sent relative to the common reference clock. Since
the same reference is available at the packet egress point and the packet size is fixed, the original service clock
frequency can be recovered. This technique is unaffected by any low frequency components in the packet delay
variation. The disadvantage is the requirement for a common reference clock at each end of the packet network,
which could either be the central office TDM clock, or provided by a global position system (GPS) receiver.

5.2 Adaptive Clock Recovery
For applications where there is no common reference clock between provider edge units, an adaptive clock
recovery technique is provided. This infers the clock rate of the original TDM service clock from the mean arrival
rate of packets at the packet egress point.
The disadvantage of this type of scheme is that, depending on the characteristics of the packet network, it may
prove difficult to regenerate a clock that stays within the wander requirements of the plesiochronous digital
hierarchy (specifically MTIE). The reason for this is that any variation in delay between packets will feed through as
a variation in the frequency of the recovered clock. High frequency jitter can be filtered out, but any low frequency
variation or wander is more difficult to remove without a very long time constant. This will in turn affect the ability of
the system to lock to the original clock within an acceptable time.
With no PRS clock the only information available to determine the TDM transmission speed is the average arrival
rate of the packets, as shown in Figure 17. Timestamps representing the number of elapsed source clock periods
may be included in the packet header, or information can be inferred from a known payload size at the destination.
It is possible to maintain average buffer-fill levels at the destination, where an increase or decrease in the fill level of
the buffer would require a change in transmission clock speed to maintain the average. Additionally, the buffer-fill
depth can be altered independently, with no relation to the recovered clock frequency, to control TDM transmission
latency.

6.0 System Features
6.1 Latency
The following lists the intrinsic processing latency of the ZL50118/19/20, regardless of the number of active
channels or contexts.
TDM to Packet transmission processing latency less than 125 µs
Packet to TDM transmission processing latency less than 250 µs (unstructured)
Packet to TDM transmission processing latency less than 250 µs (structured, more than 16 channels in
context)
Packet to TDM transmission processing latency less than 375 µs (structured, 16 or less channels in context)
End-to-end latency may be estimated as the transmit latency + packet network latency + receive latency. The
transmit latency is the sum of the transmit processing and the number of frames per packet x 125 µs. The receive
latency is the sum of the receive processing and the delay through the jitter buffer which is programmed to
compensate for packet network PDV.
The ZL50118/19/20 is capable of creating an extremely low latency connection, with end to end delays of less than
0.5 ms, depending on user configuration.
6.2 Loopback Modes
The ZL50118/19/20 devices support loopback of the TDM circuits and the circuit emulation packets.
TDM loopback is achieved by first packetizing the TDM circuit as normal via the TDM Interface and Payload
Assembly blocks. The packetized data is then routed by the Task Manager back to the same TDM port via the TDM
Formatter and TDM Interface.
Loopback of the emulated services is achieved by redirecting classified packets from the Packet Receive blocks,
back to the packet network. The Packet Transmit blocks are setup to strip the original header and add a new
header directing the packets back to the source.
6.3 Host Packet Generation
The control processor can generate packets directly, allowing it to use the network for out-of-band communications.
This can be used for transmission of control data or network setup information, e.g., routing information. The host
interface can also be used by a local resource for network transmission of processed data.
The device supports dual address DMA transfers of packets to and from the CPU memory, using the host's own
DMA controller. Table 22 illustrates the maximum bandwidths achievable by an external DMA master.

Note 1: Maximum bandwidths are the maximum the ZL50118/19/20 devices can transfer under host control, and assumes only
minimal packet processing by the host.
Note 2: Combined figures assume the same amount of data is to be transferred each way.
6.4 Loss of Service (LOS)
During normal transmission a situation may arise where a Loss of Service occurs, caused by a disruption in the
transmission line due to engineering works or cable disconnection for example. This results in the loss of a TDM
signal, including the associated TDM clock, from the LIU.
With no TDM signal or clock, no packets can be assembled by the transmitting ZL50118/19/20 device, and the flow
of packets will cease. The absence of packets at the receiving ZL50118/19/20 device will cause underrun data to be
generated at the TDM output, normally an “all-ones” pattern, with the exception of DS3 which alternates ones and
zeros. The LOS condition is detected by the receive ZL50118/19/20 device.
Additionally, when the LIU detects LOS, it can notify the CPU. The CPU can set a control bit in the packet header
(bit L in the IETF drafts), which is then transmitted. The receiving ZL50118/19/20 device recognizes the control bit,
and transmits an AIS (all-ones) pattern on the appropriate TDM stream.
Using both mechanisms provides a robust method of indicating an LOS condition to the downstream TDM
equipment.
6.5 Power Up sequence
To power up the ZL50118/19/20 the following procedure must be used:
The Core supply must never exceed the I/O supply by more than 0.5VDC
Both the Core supply and the I/O supply must be brought up together
The System Reset and, if used, the JTAG Reset must remain low until at least 100 µs after the 100 MHz
system clock has stabilised. Note that if JTAG Reset is not used it must be tied low
This is illustrated in the diagram shown in Figure 18.

6.9 Test Modes Operation
6.9.1 Overview
The ZL50118/19/20 family supports the following modes of operation.
6.9.1.1 System Normal Mode
This mode is the device's normal operating mode. Boundary scan testing of the peripheral ring is accessible in this
mode via the dedicated JTAG pins. The JTAG interface is compliant with the IEEE Std. 1149.1-2001; Test Access
Port and Boundary Scan Architecture.
Each variant has it's own dedicated.bsdl file which fully describes it's boundary scan architecture.
6.9.1.2 System Tri-State Mode
All output and I/O output drivers are tri-stated allowing the device to be isolated when testing or debugging the
development board.
6.9.2 Test Mode Control
The System Test Mode is selected using the dedicated device input bus TEST_MODE[2:0] as follows in Table 23.
6.9.3 System Normal Mode
Selected by TEST_MODE[2:0] = 3'b000. As the test_mode[2:0] inputs have internal pull-downs this is the default
mode of operation if no external pull-up/downs are connected. The GPIO[15:0] bus is captured on the rising edge of
the external reset to provide internal bootstrap options. After the internal reset has been de-asserted the GPIO pins
may be configured by the ADM module as either inputs or outputs.
6.9.4 System Tri-state Mode
Selected by TEST_MODE[2:0] = 3'b011. All device output and I/O output drivers are tri-stated.

7.0 DPLL Specification
The ZL50118/19/20 family incorporates an internal DPLL that meets Telcordia GR-1244-CORE Stratum 3 and
Stratum 4/4E requirements, assuming an appropriate clock oscillator is connected to the system clock pin. It will
meet the jitter/wander tolerance, jitter/wander transfer, intrinsic jitter/wander, frequency accuracy, capture range,
phase change slope, holdover frequency and MTIE requirements for these specifications. In structured mode with
the ZL50118/19/20 device operating as a master the DPLL is used to provide clock and frame reference signals to
the internal and external TDM infrastructure. In structured mode, with the ZL50118/19/20 device operating as a
slave, the DPLL is not used. All TDM clock generation is performed externally and the input streams are
synchronised to the system clock by the TDM interface. The DPLL is not required in unstructured mode, where
TDM clock and frame signals are generated by internal DCO’s assigned to each individual stream.
7.1 Modes of Operation
It can be set into one of four operating modes: Locking mode, Holdover mode, Freerun mode and Powerdown
mode.
7.1.1 Locking Mode (normal operation)
The DPLL accepts a reference signal from either a primary or secondary source, providing redundancy in the event
of a failure. These references should have the same nominal frequencies but do not need to be identical as long as
their frequency offsets meet the appropriate Stratum requirements. Each source is selected from any one of the
available TDM input stream clocks (up to 4 on the ZL50120 variant), or from the external TDM_CLKiP (primary) or
TDM_CLKiS (secondary) input pins, as illustrated in Figure 12 - on page 48. It is possible to supply a range of input
frequencies as the DPLL reference source, depicted in Table 24. The PRD register Value is the number (in
hexadecimal) that must be programmed into the PRD register within the DPLL to obtain the divided down frequency
at PLL_PRI or PLL_SEC.
Note 1: A PRD/SRD value of 0 will suppress the clock, and prevent it from reaching the DPLL.
Note 2: UI means Unit Interval - in this case periods of the time signal. So ±1UI on a 64 kHz signal means ±15.625 µs, the period of
the reference frequency. Similarly ±1023UI on a 4.096 MHz signal means ±250 µs.
Note 3: This input frequency is supported with the use of an external divide by 2.

Table 24 - DPLL Input Reference Frequencies

The maximum lock-in range can be programmed up to ±372 ppm regardless of the input frequency. The DPLL will
fail to lock if the source input frequency is absent, if it is not of approximately the correct frequency or if it is too
jittery. See Section 7.7 for further details. Limitations depend on the users programmed values, so the DPLL must
be programmed properly to meet Stratum 3, or Stratum 4/4E. The Application Program Interface (API) software that
accompanies the ZL50118/19/20 family can be used to automatically set up the DPLL for the appropriate standard
requirement.
The DPLL lock-in range can be programmed using the Lock Range register (see ZL50118/19/20 Programmers
Model document) in order to extend or reduce the capture envelope. The DPLL provides bit-error-free reference
switching, meeting the specification limits in the Telcordia GR-1244-CORE standard. If Stratum 3 or Stratum 4/4E
accuracy is not required, it is possible to use a more relaxed system clock tolerance.
The DPLL output consists of three signals; a common clock (comclk), a double-rate common clock (comclkx2) and
a frame reference (8 kHz). These are used to time the internal TDM Interface, and hence the corresponding TDM
infrastructure attached to the interface. The output clock options are either 2.048 Mbps (comclkx2 at 4.096 Mbps)
or 8.192 Mbps (comclkx2 at 16.384 Mbps), determined by setup in the DPLL control register. The frame pulse is
programmable for polarity and width.
7.1.2 Holdover Mode
In the event of a reference failure resulting in an absence of both the primary and secondary source, the DPLL
automatically reverts to Holdover mode. The last valid frequency value recorded before failure can be maintained
within the Stratum 3 limits of ±0.05 ppm. The hold value is wholly dependent on the drift and temperature
performance of the system clock. For example, a ±32 ppm oscillator may have a temperature coefficient of
±0.1 ppm/°C. Thus a 10°C ambient change since the DPLL was last in the Locking mode will change the holdover
frequency by an additional ±1 ppm, which is much greater than the ±0.05 ppm Stratum 3 specification. If the strict
target of Stratum 3 is not required, a less restrictive oscillator can be used for the system clock.
Holdover mode is typically used for a short period of time until network synchronisation is re-established.
7.1.3 Freerun Mode
In freerun mode the DPLL is programmed with a centre frequency, and can output that frequency within the
Stratum 3 limits of ±4.6 ppm. To achieve this the 100 MHz system clock must have an absolute frequency accuracy
of ±4.6 ppm. The centre frequency is programmed as a fraction of the system clock frequency.
7.1.4 Powerdown Mode
It is possible to “power down” the DPLL when it is not in use. For example, an unstructured TDM system, or use of
an external DPLL would mean the internal DPLL could be switched off, saving power. The internal registers can still
be accessed while the DPLL is powered down.
7.2 Reference Monitor Circuit
There are two identical reference monitor circuits, one for the primary and one for the secondary source. Each
circuit will continually monitor its reference, and report the references validity. The validity criteria depends on the
frequency programmed for the reference. A reference must meet all the following criteria to maintain validity:
The “period in specified range” check is performed regardless of the programmed frequency. Each period
must be within a range, which is programmable for the application. Refer to the ZL50118/19/20 programmers
model for details.
If the programmed frequency is 1.544 MHz or 2.048 MHz, the “n periods in specified range” check will be
performed. The time taken for n cycles must be within a programmed range, typically with n at 64, the time
taken for consecutive cycles must be between 62 and 66 periods of the programmed frequency.
ZL50118/19/20 Data Sheet

Zarlink Semiconductor Inc.
The fail flags are independent of the preferred option for primary or secondary operation, will be asserted in the
event of an invalid signal regardless of mode.
7.3 Locking Mode Reference Switching
When the reference source the DPLL is currently locking to becomes invalid, the DPLL’s response depends on
which one of the failure detect modes has been chosen: autodetect, forced primary, or forced secondary. One of
these failure detect modes must be chosen via the FDM1:0 bits of the DOM register. After a device reset via the
SYSTEM_RESET pin, the autodetect mode is selected.
In autodetect mode (automatic reference switching) if both references are valid the DPLL will synchronise to the
preferred reference. If the preferred reference becomes unreliable, the DPLL continues driving its output clock in a
stable holdover state until it makes a switch to the backup reference. If the preferred reference recovers, the DPLL
makes a switch back to the preferred reference. If necessary, the switch back can be prevented by changing the
preferred reference using the REFSEL bit in the DOM register, after the switch to the backup reference has
occurred.
If both references are unreliable, the DPLL will drive its output clock using the stable holdover values until one of
the references becomes valid.
In forced primary mode, the DPLL will synchronise to the primary reference only. The DPLL will not switch to the
secondary reference under any circumstances including the loss of the primary reference. In this condition, the
DPLL remains in holdover mode until the primary reference recovers. Similarly in forced secondary mode, the
DPLL will synchronise to the secondary reference only, and will not switch to the primary reference. Again, a failure
of the secondary reference will cause the DPLL to enter holdover mode, until such time as the secondary reference
recovers. The choice of preferred reference has no effect in these modes.
When a conventional PLL is locked to its reference, there is no phase difference between the input reference and
the PLL output. For the DPLL, the input references can have any phase relationship between them. During a
reference switch, if the DPLL output follows the phase of the new reference, a large phase jump could occur. The
phase jump would be transferred to the TDM outputs. The DPLL’s MTIE (Maximum Time Interval Error) feature
preserves the continuity of the DPLL output so that it appears no reference switch had occurred. The MTIE circuit is
not perfect however, and a small Time Interval Error is still incurred per reference switch. To align the DPLL output
clock to the nearest edge of the selected input reference, the MTIE reset bit (MRST bit in the DOM register) can be
used.
Unlike some designs, switching between references which are at different nominal frequencies do not require
intervention such as a system reset.
7.4 Locking Range
The locking range is the input frequency range over which the DPLL must be able to pull into synchronization and to
maintain the synchronization. The locking range is programmable up to ±372 ppm.
Note that the locking range relates to the system clock frequency. If the external oscillator has a tolerance of
-100 ppm, and the locking range is programmed to ±200 ppm, the actual locking range is the programmed value
shifted by the system clock tolerance to become -300 ppm to +100 ppm.
7.5 Locking Time
The Locking Time is the time it takes the synchroniser to phase lock to the input signal. Phase lock occurs when the
input and output signals are not changing in phase with respect to each other (not including jitter).
ZL50118/19/20 Data Sheet
61
Zarlink Semiconductor Inc.
Locking time is very difficult to determine because it is affected by many factors including:
initial input to output phase difference
initial input to output frequency difference
DPLL Loop Filter
DPLL Limiter (phase slope)
Although a short phase lock time is desirable, it is not always achievable due to other synchroniser requirements.
For instance, better jitter transfer performance is obtained with a lower frequency loop filter which increases locking
time; and a better (smaller) phase slope performance will increase locking time. Additionally, the locking time is
dependent on the p_shift value.
The DPLL Loop Filter and Limiter have been optimised to meet the Telcordia GR-1244-CORE jitter transfer and
phase alignment speed requirements. The phase lock time is guaranteed to be no greater than 30 seconds when
using the recommended Stratum 3 and Stratum 4/4E register settings.
7.6 Lock Status
The DPLL has a Lock Status Indicator and a corresponding Lock Change Interrupt. The response of the Lock
Status Indicator is a function of the programmed Lock Detect Interval (LDI) and Lock Detect Threshold (LDT) values
in the dpll_ldetect register. The LDT register can be programmed to set the jitter tolerance level of the Lock Status
Indicator. To determine if the DPLL has achieved lock the Lock Status Indicator must be high for a period of at least
30 seconds. When the DPLL loses lock the Lock Status Indicator will go low after LDI x 125 µs.
7.7 Jitter
The DPLL is designed to withstand, and improve inherent jitter in the TDM clock domain.
7.7.1 Acceptance of Input Wander
For T1(1.544 MHz), E1(2.048 MHz) and J2(6.312 MHz) input frequencies, the DPLL will accept a wander of up to
±1023UIpp at 0.1 Hz to conform with the relevant specifications. For the 8 kHz (frame rate) and 64 kHz (the divided
down output for T3/E3) input frequencies, the wander acceptance is limited to ±1 UI (0.1 Hz). This principle is
illustrated in Table 24.
7.7.2 Intrinsic Jitter
Intrinsic jitter is the jitter produced by a synchronizer and measured at its output. It is measured by applying a jitter
free reference signal to the input of the device, and measuring its output jitter. Intrinsic jitter may also be measured
when the device is in a non synchronizing mode such as free running or holdover, by measuring the output jitter of
the device. Intrinsic jitter is usually measured with various band-limiting filters, depending on the applicable
standards.
The intrinsic jitter in the DPLL is reduced to less than 1 ns p-p1 by an internal Tapped Delay Line (TDL). The DPLL
can be programmed so that the output clock meets all the Stratum 3 requirements of Telcordia GR-1244-CORE.
Stratum 4/4E is also supported.
1. There are 2 exceptions to this. a) When reference is 8 kHz, and reference frequency offset relative to the master is small, jitter up to 1 master
clock period is possible, i.e. 10 ns p-p. b) In holdover mode, if a huge amount of jitter had been present prior to entering holdover, then an
additional 2 ns p-p is possible.

7.7.3 Jitter Tolerance
Jitter tolerance is a measure of the ability of a PLL to operate properly without cycle slips (i.e., remain in lock and/or
regain lock in the presence of large jitter magnitudes at various jitter frequencies) when jitter is applied to its
reference. The applied jitter magnitude and the jitter frequency depends on the applicable standards.
The DPLL’s jitter tolerance can be programmed to meet Telcordia GR-1244-CORE DS1 reference input jitter
tolerance requirements.
7.7.4 Jitter Transfer
Jitter transfer or jitter attenuation refers to the magnitude of jitter at the output of a device for a given amount of jitter
at the input of the device. Input jitter is applied at various amplitudes and frequencies, and output jitter is measured
with various filters depending on the applicable standards.
Since intrinsic jitter is always present, jitter attenuation will appear to be lower for small input jitter signals than
larger ones. Consequently, accurate jitter transfer function measurements are usually made with large input jitter
signals (e.g. 75% of the specified maximum jitter tolerance).
The internal DPLL is a first order type 2 component, so a frequency offset doesn’t result in a phase offset. Stratum
3 requires a -3 dB frequency of less than 3 Hz. The nature of the filter results in some peaking, resulting in a -3dB
frequency of 1.9 Hz and a 0.08 dB peak with a system clock frequency of 100 MHz assuming a p_shift value of 2.
The transfer function is illustrated in Figure 19 and in more detail in Figure 20. Increasing the p_shift value
increases the speed the DPLL will lock to the required frequency and reduces the peak, but also reduces the
tolerance to jitter - so the p_shift value must be programmed correctly to meet Stratum 3 or Stratum 4/4E jitter
transfer characteristics. This is done automatically in the API.
7.8 Maximum Time Interval Error (MTIE)
In order to meet several standards requirements, the phase shift of the DPLL output must be controlled. A potential
phase shift occurs every time the DPLL is re-arranged by changing reference source signal, or the mode. In order
to meet the requirements of Stratum 3, the DPLL will shift phase by no more than 20 ns per re-arrangement.
Additionally the speed at which the change occurs is also critical. A large step change in output frequency is
undesirable. The rate of change is programmable using the skew register, up to a maximum of 15.4 ns / 125 µs
(124 ppm).

Note 3: tDOZ and tZDO apply at every time-slot boundary.
Note 4: Refer to H.110 Standard from Enterprise Computer Telephony Forum (ECTF) for the source of these numbers.
Note 5: The TDM_FRAME signal is centred on the rising edge of TDM_C8. All timing measurements are based on this rising edge
point; TDM_FRAME corresponds to pin TDM_F0i.
Note 6: Phase correction (Φ) results from DPLL timing corrections.

10.4 TDM LIU Interface Timing
The TDM Interface can be used to directly drive into a Line Interface Unit (LIU). The interface can work in this mode
with E1, DS1, J2, E3 and DS3. The frame pulse is not present, just data and clock is transmitted and received.
Table 28 shows timing for DS3, which would be the most stringent requirement.

10.8 System Function Port
Note 1: The system clock frequency stability affects the holdover-operating mode of the DPLL. Holdover Mode is typically used for a
short duration while network synchronisation is temporarily disrupted. Drift on the system clock directly affects the Holdover
Mode accuracy. Note that the absolute system clock accuracy does not affect the Holdover accuracy, only the change in the
system clock (SYSTEM_CLK) accuracy while in Holdover. For example, if the system clock oscillator has a temperature
coefficient of 0.1 ppm/ºC, a 10ºC change in temperature while the DPLL is in will result in a frequency accuracy offset of
1 ppm. The intrinsic frequency accuracy of the DPLL Holdover Mode is 0.06 ppm, excluding the system clock drift.
Note 2: The system clock frequency affects the operation of the DPLL in free-run mode. In this mode, the DPLL provides timing and
synchronisation signals which are based on the frequency of the accuracy of the master clock (i.e., frequency of clock output
equals 8.192 MHz ± SYSTEM_CLK accuracy ± 0.005 ppm).
Note 3: The absolute SYSTEM_CLK accuracy must be controlled to ± 30 ppm in synchronous master mode to enable the internal
DPLL to function correctly.
Note 4: In asynchronous mode and in synchronous slave mode the DPLL is not used. Therefore the tolerance on SYSTEM_CLK may
be relaxed slightly.

12.0 Design and Layout Guidelines
This guide will provide information and guidance for PCB layouts when using the ZL50118/19/20. Specific areas of
guidance are:
High Speed Clock and Data, Outputs and Inputs
CPU_TA Output
12.1 High Speed Clock & Data Interfaces
On the ZL50118/19/20 series of devices there are four high-speed data interfaces that need consideration when
laying out a PCB to ensure correct termination of traces and the reduction of crosstalk noise. The interfaces being:
GMAC Interfaces
TDM Interface
CPU Interface
It is recommended that the outputs are suitably terminated using a series termination through a resistor as close to
the output pin as possible. The purpose of the series termination resistor is to reduce reflections on the line. The
value of the series termination and the length of trace the output can drive will depend on the driver output
impedance, the characteristic impedance of the PCB trace (recommend 50 ohm), the distributed trace capacitance
and the load capacitance. As a general rule of thumb, if the trace length is less than 1/6th of the equivalent length of
the rise and fall times, then a series termination may not be required.
the equivalent length of rise time = rise time (ps) / delay (ps/mm)
For example:
Typical FR4 board delay = 6.8 ps/mm
Typical rise/fall time for a ZL50118/19/20 output = 2.5 ns
critical track length = (1/6) x (2500/6.8) = 61 mm
Therefore tracks longer than 61 mm will require termination.
As a signal travels along a trace it creates a magnetic field, which induces noise voltages in adjacent traces, this is
crosstalk. If the crosstalk is of sufficiently strong amplitude, false data can be induced in the trace and therefore it
should be minimized in the layout. The voltage that the external fields cause is proportional to the strength of the
field and the length of the trace exposed to the field. Therefore to minimize the effect of crosstalk some basic
guidelines should be followed.
First, increase separation of sensitive signals, a rough rule of thumb is that doubling the separation reduces the
coupling by a factor of four. Alternatively, shield the victim traces from the aggressor by either routing on another
layer separated by a power plane (in a correctly decoupled design the power planes have the same AC potential) or
by placing guard traces between the signals usually held ground potential.
Particular effort should be made to minimize crosstalk from ZL50118/19/20 outputs and ensuring fast rise time to
these inputs.

Place series termination resistors as close to the pins as possible
minimize output capacitance
Keep common interface traces close to the same length to avoid skew
Protect input clocks and signals from crosstalk
12.1.1 GMAC Interface - Special Considerations During Layout
The GMII interface passes data to and from the ZL50118/19/20 with their related transmit and receive clocks. It is
therefore recommended that the trace lengths for transmit related signals and their clock and the receive related
signals and their clock are kept to the same length. By doing this the skew between individual signals and their
related clock will be minimized.
12.1.2 TDM Interface - Special Considerations During Layout
Although the data rate of this interface is low the outputs edge speeds share the characteristics of the higher data
rate outputs and therefore must be treated with the same care extended to the other interfaces with particular
reference to the lower stream numbers which support the higher data rates. The TDM interface has numerous
clocking schemes and as a result of this the input clock traces to the ZL50118/19/20 devices should be treated with
care.
12.1.3 Summary
Particular effort should be made to minimize crosstalk from ZL50118/19/20 outputs and ensuring fast rise time to
these inputs.
In Summary:
Place series termination resistors as close to the pins as possible
minimize output capacitance

12.2 CPU TA Output
The CPU_TA output signal from the ZL50118/19/20 is a critical handshake signal to the CPU that ensures the
correct completion of a bus transaction between the two devices. As the signal is critical, it is recommend that the
circuit shown in Figure 43 is implemented in systems operating above 40 MHz bus frequency to ensure robust
operation under all conditions.
The following external logic is required to implement the circuit:
74LCX74 dual D-type flip-flop (one section of two)
74LCX08 quad AND gate (one section of four)
74LCX125 quad tri-state buffer (one section of four)
4K7 resistor x2
Figure 43 - CPU_TA Board Circuit
The function of the circuit is to extend the TA signal, to ensure the CPU correctly registers it. Resistor R2 must be
fitted to ensure correct operation of the TA input to the processor. It is recommended that the logic is fitted close to
the ZL50118/19/20 and that the clock to the 74LCX74 is derived from the same clock source as that input to the
ZL50118/19/20.
