Figure 1. Functional Block Diagram
The PanelLink TMDS core accepts as inputs the three TMDS differential data lines and the differential clock. The
core senses the signals on the link and properly decodes them providing accurate pixel data. The core outputs
the necessary sync signals (HSYNC, VSYNC), clock (ODCK), and a DE signal that goes high when the active
region of the video is present.
The SCDT signal is output when there is active video on the DVI link and the PLL in the TMDS has locked on to
the video. SCDT can be used to trigger external circuitry, indicating that an active video signal is present or used
to place the device in power down when no signal is present (by tying it to PD#). The EXT_RES component is
used for impedance matching.
When Single/Dual Link Mode (S_D) is HIGH, the signals M_S and SYNC are used to select and coordinate
operation of two receivers in a dual-link DVI configuration. In this mode, at frequencies up to 165 MHz, the
master receiver outputs two pixels/clock (48 data bits). At frequencies above 165 MHz, the master outputs even
pixels (24 bits) while the slave receiver outputs odd pixels (24 bits) synchronized with one DE output from the
master.

Notes on previous table:
1. Guaranteed by design.
2. Jitter defined per DVI 1.0 Specification, Section 4.6 – Jitter Specification.
3. Jitter measured with Clock Recovery Unit per DVI 1.0 Specification, Section 4.7 – Electrical Measurement Procedures.
4. Output clock duty cycle is independent of the differential input clock duty cycle and the IDCK duty cycle.
5. Measured with transmitter powered down.
6. Value in parentheses is specified with OCK_INV#=1.
7. Skew between output data buses when two SiI 163B are wired in master-slave configuration for dual-link. See the
Receiver Layout section on page 30. The ‘minimum’ is the limit of Slave leading Master (slave data output earlier than
master data). The ‘maximum’ is the limit of Slave lagging Master (slave data output later than master data). When the
Slave lags the Master, then the setup time available from Slave data to ODCK (from the Master) is reduced.
Setup and Hold Timings for Data Rates other than 165 MHz
The measurements shown above are minimum setup and hold timings based on the maximum data rate of 165
MHz. To estimate the setup and hold times for slower data rates (for either different resolutions or 2 pixel per
clock mode), the following formula can be used:
Time (at new frequency) = Time (165 MHz) + (Clock Period at new frequency – Clock Period at 165 MHz)/2
For the case of high strength output (ST=1) with a 10pf load, and using the standard ODCK (OCK_INV# = 0),
Table 1 shows the minimum set up and hold times for other speeds as follows:

Designers may want to check whether OCK+INV#=0 or OCK_INV#=1 provides better setup and hold time margin
for their dual-link design. If Slave data lags Master data, which is in part determined by the layout, then the setup
time from Slave to clock may be reduced, and the opposite ODCK edge may be more useful.

Feature Information
The SiI 163B can be configured in two modes: Single Link and Dual Link. When in Single Link (S_D is LOW), the
device operates in either 1-pixel/clock or 2-pixel/clock mode, according to the state of the PIXS pin. There is no
communication with a second receiver. In this mode, the SiI 163B operates in the same way as the other
PanelLink receivers: SiI 143B, SiI 151B, SiI 153B and SiI 161B.
In Dual Link mode, two SiI 163B’s operate together to handle bandwidths up to 330 megapixels per second. The
configuration and management of this mode is detailed in the following sections. Dual Link mode may operate
across a pixel frequency of 25 MHz to 330 MHz. Below 165 MHz, the second TMDS channel is quiescent. All
pixel data is sent across the first TMDS channel, and handled by the Master SiI 163B receiver. Above 165 MHz,
both SiI 163B receivers are active, with the pixels alternating even-and-odd from Master to Slave, driven by the
two TMDS DVI channels.
Dual Link
Two SiI 163B’s are required for a DVI compatible Dual Link application as configured in the block diagram of
Figure 11. At pixel frequencies up to 165 MHz, the system does not send any data over the second link
connected to the Slave receiver. Therefore, the Slave receiver is not active and its outputs are tri-stated. All the
data, both EVEN and ODD pixels, are sent over the TMDS link connected to the Master receiver. Therefore all the
data, both EVEN and ODD pixels, is output by the Master receiver.
At pixel frequencies above 165 MHz, the system sends EVEN data over the link connected to the Master receiver
and the ODD data over the link connected to the Slave receiver. Therefore, the EVEN data is output by the
Master receiver and the ODD data is output by the Slave receiver. The Master receiver’s ODD data bus is tri-
stated to allow the Slave receiver’s EVEN Data bus to output the ODD data.
Dual Link Configuration Pins
Five pins on the SiI 163B need to be considered for Dual Link receiver applications.
Table 2. SiI 163B Dual Link Pin Definitions
Pin Name Pin # Type Description
S_D 1 In Single/Dual Link Mode. When HIGH, it is in Dual Link Mode. When LOW it is
in Single Link Mode. The Slave receiver is always in Dual Link mode. The
Master receiver switches between Single and Dual Link mode depending
upon the SCDT output of the Slave receiver that is connected to the S_D
input of the Master receiver.
PIXS / M_S 4 In Master/Slave. When S_D pin is HIGH (Dual Link), this pin becomes M_S.
When HIGH, it is in Master mode. When LOW, it is in Slave mode. The
Master receiver is in one/two-pixels per clock mode depending upon
Single/Dual Link operation. The Slave receiver is always in one-pixel per
clock mode.
When S_D is LOW (Single Link), this pin becomes PIXS.
STAG_OUT /
SYNC
7 In Synchronization. When S_D pin is HIGH (Dual Link), this pin is used to
synchronize the Slave receiver to the Master receiver. The SYNC input pin of
the Slave receiver is connected to the DE output pin of the Master receiver.
SCDT 8 Out Sync Detect. When HIGH, there are valid sync signals coming from the
transmitter. When LOW, there are no sync signals coming from the
transmitter. The SCDT pin of the Slave receiver is connected to the S_D pin
of the Master receiver.
DE 46 Out Data Enable. This signal qualifies the active data area. A HIGH level signifies
active display time and a LOW level signifies blanking time. This output signal
is synchronized with the output data.
The DE output pin of the Master is connected to the SYNC input pin of the
Slave.

Master –
The Master receiver will automatically configure to either Single or Dual Link operation (two or one pixel
per clock mode, respectively) depending on the transmitter system output. This is accomplished by
connecting the SCDT output pin of the Slave to the S_D pin on the Master. When the transmitter sends
data on the second link, the SCDT output of the slave (and the S_D pin on the Master) is driven HIGH,
setting to Dual Link (one-pixel per clock) mode. If there is no data on the second link, the SCDT output of
the Slave (and the S_D pin on the Master) is driven LOW, and the Master receiver is in Single Link (two-
pixels per clock) mode.
The Master receiver is configured by pulling the M_S pin to HIGH. When it is in Dual Link mode, the
Master receiver is in one-pixel per clock mode outputting the EVEN data. The Master receiver’s ODD
data bus is tri-stated to allow the Slave receiver’s EVEN data bus to be used as the ODD data bus. When
it is in Single Link mode, the Master receiver is in two-pixels per clock mode outputting both the EVEN
and ODD data. The Slave receiver’s EVEN data bus is tri-stated to allow the Master receiver’s ODD data
bus to be used as the ODD data.
The DE output pin of the Master receiver is connected to the SYNC input pin of the Slave receiver. This is
used for output synchronization between the Master receiver and Slave receiver. DE, HSYNC, VSYNC,
and ODCK are all connected from the Master receiver.
Slave – The Slave receiver is always configured for Dual Link (one pixel/clock) operation, by tying the S_D pin to
HIGH. The Slave receiver is never used in Single Link mode since the Master receiver is the primary
receiver for Single Link Operation.
The Slave receiver is configured by tying the M_S pin to LOW. The Slave receiver will always contain the
ODD data bus in Dual Link operation. Therefore, it will never be in two-pixels per clock mode.
The SCDT output pin of the Slave receiver is connected to the S_D input pin of the Master receiver to
automatically configure the Master for either Single or Dual Link mode depending upon whether the Slave
receiver is active or not.
The SYNC input pin of the Slave receiver is connected to the DE output pin of the Master receiver for
synchronization.
Since DE, HSYNC, VSYNC, and ODCK are all taken from the Master receiver, these pins are not
connected from the Slave receiver.

Dual Link Power Management
Power management with PD# and PDO# is slightly different in a Dual Link design than a Single Link.
When the receivers are in dual-link mode (S_D=1), then the connection from SCDT to PDO# is internal.
A receiver which detects no activity at the TMDS inputs will deassert SCDT, which will then put that chip
into power-down-output mode. This is the process which enables the slave receiver to tri-state its outputs
whenever it stops receiving data.
The outputs may also be directly tri-stated by asserting the PDO# pin.
Receivers will also enter a low-power state when the differential TMDS clock stops. The receiver
awakens when the clock resumes, at which point the receiver begins checking for active data. Active
data will assert SCDT and put the chip back into full-power mode.
Dual Link Mode Selection
Single Link Mode –
In Single Link mode, the Slave receiver is not active. Its outputs are all tri-stated. The Slave receiver will
detect that there is no signal coming from the transmitter and de-assert SCDT to LOW. The SCDT pin
from the Slave receiver is connected to the Master receiver’s S_D pin. This will cause the S_D pin of the
Master receiver to be LOW that will cause the Master receiver to be in Single Link mode. Since the
Master receiver is in Single Link mode, it will output two-pixels per clock. All the Data, both EVEN and
ODD pixels, will be output from the Master receiver. The Slave receivers EVEN Data bus is tri-stated to
allow the Master receiver’s ODD Data bus to be used as the ODD Data.
Dual Link Mode –
In Dual Link mode, the Slave receiver is active. The Slave receiver will detect that there are valid signals
coming from the transmitter and assert SCDT to HIGH. This will cause the S_D pin of the Master receiver
to be HIGH that will cause the Master receiver to be in Dual Link mode. This will also cause the Master
receiver to tri-state its Odd Data bus to allow the Slave receiver’s EVEN Data bus to be used as the ODD
Data. The Master receiver will output the EVEN Data. When there are no sync signals coming from the
transmitter, both the Slave and Master receiver’s outputs are tri-stated automatically.
The STAG_OUT pin of the Slave receiver is not used in one-pixel per clock mode, so this takes on a
different meaning in Dual Link mode. It becomes SYNC input pin. This pin is used for synchronization
between the Master and Slave receivers. The DE output pin from the Master receiver is connected to the
SYNC input pin of the Slave receiver.

Dual Link Timing Diagrams
Below in Figure 12 is an example of the output timing diagram of the Master receiver. When the Slave receiver’s
SCDT signal is LOW, the Slave receiver is inactive and has tri-stated all its data outputs. This is because the
system is sending data with a pixel clock of less than or equal to 165. The DVI link uses the Master receiver only.
There are no signals being sent to the Slave receiver from the system. The Master receiver is in Single Link 2-
pixel/clock mode and outputs the pixel data, both EVEN and ODD pixels.
When the Slave receiver’s SCDT signal goes HIGH, the system is sending sata with a pixel clock greater than
165 MHz and less then 330 MHz. The system is sending the EVEN pixel to the Master receiver and the ODD
pixel to the Slave receiver. The Slave receiver is receiving signals from the system and has asserted its SCDT
signal to the Master receiver. This puts the Master receiver in Dual Link 1-pixel/clock mode. The Slave receiver
outputs the ODD pixel data. The Master receiver outputs the EVEN pixel data. The Master receiver has tri-stated
its ODD pixel bus to allow the Slave receiver to send ODD pixel data.

Figure 13 is an example of the output timing diagram of the Slave receiver. When the Slave receiver’s SCDT

There are no signals being sent to the Slave receiver from the system.
When the Slave receiver’s SCDT signal goes HIGH, the system is sending data with a pixel clock greater than

outputting the ODD pixel data on its EVEN pixel bus. The Master receiver outputs the EVEN pixels. The Master

Clock Detect Function
The SiI 163B includes a new power saving feature: power down with clock detect circuit. The SiI 163B will go into
a low power mode when there is no video clock coming from the transmitter. In this mode, the entire chip is
powered down except the clock detect circuitry. During this mode, digital I/O are set to a high impedance (tri-
state) mode. A weak internal pull-down device brings each output to ground. The device power down and wake-
up times are shown in Figure 6 and Figure 7.
OCK_INV# Function
OCK_INV# affects only the phase of the clock output as
indicated in Figure 15. OCK_INV# does not change the
timing for the internal data latching. This timing is
shown in Figure 5.

TFT Panel Data Mapping
Table 5 summarizes the output data mapping in one pixel per clock mode for the SiI 163B. This output data
mapping is dependent upon the PanelLink transmitters having the exact same type of input data mappings.
Table 6 summarizes the output data mapping in two pixel per clock mode. More detailed mapping information is
found on the following pages. Refer to application note SiI-AN-0007 for DSTN applications.
Note that the choice of one pixel/clock versus two pixel/clock on the transmitter side has no effect on the choice of
one pixel/clock versus two pixel/clock on the receiver side. The data is always sent across the link at the pixel
clock rate. Therefore, designers using PanelLink receivers do not need to know how the transmitter has taken in
pixel data on the transmitter input pins.

justified. The data is sent during active display time while the control signals are sent during blank time. Note that
the three data channels (CH0, CH1, CH2) are mapped to Blue, Green and Red data respectively.

by running the extra blanked clock through an unused data pin. This works only at one pixel per clock mode, and
only when the 24 data bits are not already used for pixel data. Such a solution also requires that the transmitter
board design input the shift clock (the blanked clock for DSTN) into the same unused data pin. By using the
SiI141B, DSTN panels may be driven without requiring any special connections on the transmitter side.

Design Recommendations
The following sections describe recommendations for robust board design with this PanelLink receiver.
Designers should include provision for these circuits in their design, and adjust the specific passive component
values according to the characterization results.
Differences Between SiI 161A and SiI 163B
While the SiI 163B is pin to pin compatible with the SiI 161A, there are minor differences in functions and
suggested external component value. When designing the SiI 163B into an existing design, note that the
recommended external resistor (EXT_RES) value has changed from 560 ohms to 390 ohms to match the
impedance of a 50 ohm cable.
Table 13 lists the differences between SiI 161A and SiI 163B. Table 14 lists SiI 161B to SiI 163B differences.

EXT_RES Resistor Value 560 ohm 390 ohm
SCDT When PDO# is asserted, a pull-up resistor is
needed on SCDT to assure high-level.
SCDT continues to drive high or low when
PDO# is asserted. No need for pull-up.
HSYNC, VSYNC, CTL[1..3] Dejitter circuit adds one pixel clock time to
time from DE fall to first edge of these
signals. This affects front-porch time for
HSYNC and VSYNC.
Dejitter circuit is always disabled.
Improved Output Drive
Strength
Refer to SiI 161A Data Sheet for specifics. Output drive strength improved for these
signals. Refer to DC Specifications on
page 4. This improves output waveforms
when driving multiple loads. Some
designs may be able to change from ST=1
to ST=0.
Clock Detect for Lower
Standby Power.
Receiver powers down when PDO# is
asserted. SCDT asserts only when the chip
detects the lack of DE pulses.
Receiver detects when the differential
input clock has stopped and powers down
the internals of the chip. Refer to ICLKI in
DC Specifications on page 4.
PDO# Low-Power Mode
Improved
PDO# assertion powers down most of the
chip.
Improved design powers down more
active circuitry, resulting in lower power
when PDO# is asserted.

HSYNC, VSYNC, CTL[1:3] Dejitter circuit improved over SiI 161A. The
DE-low to first-edge time for these signals is
identical to the timing input to the
transmitter. Dejitter circuit may be enabled
or disabled using a pin.

schematically in Figure 19. Place these components as closely as possible to the PanelLink device pins, and
avoid routing through vias if possible, as shown in Figure 18, which is representative of the various types of power
pins on the receiver.

Series Damping Resistors on Outputs
Series resistors are effective in lowering the data-related emissions and reducing reflections. Series resistors

Receiver Layout
Figure 21 to Figure 23 show an example routing of Dual Link for a DVI connector to the two SiI 163B’s. The
differential clock lines must be routed to the Slave receiver first, then to the Master receiver because of the way
the internal impedance matching circuit is configured.

Figure 21. DVI Dual Link Rx PCB Routing Example – Top View
When operating as a Dual Link system, the two SiI 163B’s must output their two data buses with synchronous
timing. As described earlier, this is done by connecting DE from the Master to SYNC on the Slave. The length of
the routed net from Master to Slave must be controlled to between 2.5 and 3.5 inches long. (This corresponds to
a flight time of 400ps to 560ps, at a propagation velocity of 160ps per inch, typical of PCB layouts.)
Similarly, the connection to the differential clock, at Slave and Master, must use routed nets which are controlled
in length. The ‘stub’ from the differential pair to the Slave RxC+ and RxC- pins must be less than 1.0 inch long
(160ps). The differential pair from the start of a the Slave’s ‘stub’ to the Master’s RxC+ and RxC- pins must be no
longer than 3 inches long (~500ps). Pull down resistors to stabilize Slave SCDT output(shown on Figure 24) can
be placed further from the Slave TMDS traces.
Differential routing or DE-to-SYNC routing longer than these limits will create a skew between Master and Slave
which may exceed what can be corrected in the receivers’ logic.

The receiver chip should be placed as closely as possible to the input connector which carries the TMDS signals.
For a system using the industry-standard DVI connector (see http://www.ddwg.org), the differential lines should
be routed as directly as possible from connector to receiver. PanelLink devices are tolerant of skews between
differential pairs, so spiral skew compensation for path length differences is not required. Each differential pair
should be routed together, minimizing the number of vias through which the signal lines are routed.
As defined in the DVI 1.0 Specification, the impedance of the traces between the connector and the receiver
should be 100 ohms differentially, and close to 50 ohms single-ended. The 100 ohm requirement is to best match
the differential impedance of the cable and connectors, to prevent reflections. The common mode currents are
very small on the TMDS interface, so differential impedance is more important than single-ended.

Stabilized TMDS Inputs
The SCDT output of the slave SiI 163B receiver indicates the presence (or absence) of display data on the TMDS
link. Both incoming TMDS clock and data will output a HIGH via SCDT indicating that the encoded DE signal and
Clock from the TMDS transmitter is being detected and the link is active. In Dual Link mode the input Clock
signal is shared between Master and Slave SiI 163B.
When functioning in Single Link (in a Dual Link application), input TMDS data for Slave SiI 163B is absent, SCDT
output of the Slave SiI 163B will go low. However, system noise or coupled noise (above 20mV) can trigger the
differential input circuits of the receiver falsely indicating that display data is being received. In this condition, the
SiI 163B can assert SCDT High, even though the input data is invalid.
The SCDT output can be stabilized by introducing an offset voltage at the differential inputs. This can be
achieved by adding pull down resistors to the appropriate inputs. A nominal value of 2K ohms provides sufficient
offset between the + and – data differential inputs. In the application circuit, any value between 1.8K ohms and
2.5K ohms can be used with minimal effect on the single ended impedance.

Three pull down resistors should be placed
on either the + or – differential data input
pins. Figure 24 illustrates each + differential
input data pin pulled down by a nominal 2K
ohm resistor. The pull down resistors can be
placed either close to the receiver or the DVI
connector based on layout efficiency. Ensure
that the trace leading to the resistor and
ground is as short as possible to reduce
capacitive loading. The TMDS Clock (RXC+
and RXC–) input pins do not require pull
down resistors since they have internal pull
down resistors.
Figure 24. Stabilizing SCDT
Staggered Outputs and Two Pixels per Clock
PanelLink receivers offer two features that can minimize the switching effects of the high-speed output data bus:
two pixels per clock mode and staggered outputs.
The receiver can output one or two pixels in each output clock cycle. By widening the bus to two pixels per clock
whenever possible, the clock speed is halved and the switching period of the data signals themselves is twice as
long as in one pixel per clock mode. Typically, SXGA-resolution and above LCD panels expect to be connected
with a 36-bit or 48-bit bus, two pixels per clock. Most XGA-resolution and below LCD panels use an 18- to 24-bit
one pixel per clock interface.
When in two pixel per clock mode, the STAG_OUT# pin on receivers provides an additional means of reducing
simultaneous switching activity. When enabled (STAG_OUT# = Low), only half of the output data pins switch
together. The other half are switched one quarter clock cycle later. Note that both pixel buses use the same
clock. Therefore, the staggered bus will have one quarter clock cycle less setup time to the clock, and one
quarter clock cycle more hold time. Board designers driving into another clocked chip should take this into
account in their timing analysis.
Silicon Image recommends the use of STAG_OUT# and the two pixel per clock mode whenever possible.
Note that these features are limited when the SiI 163B is connected in Dual Link configuration.

The ePad must not be electrically connected to any other voltage level except ground (GND). A clearance of at
least 0.25mm should be designed on the PCB between the edge of the ePad and the inner edges of the lead
pads to avoid any electrical shorts. Dimensions T1 and T2 define the maximum limit of ePad size. Protrusions
from the edges of the ePad may vary slightly from one package assembler to another, but all are confined to
within these maximum dimensions.

PCB Thermal Land Area
The thermal land area on the PCB may use thermal vias to improve heat removal from the package. These
thermal vias can double as ground connections, attaching internally in the PCB to the ground plane. An array of
vias should be designed into the PCB beneath the package. For optimum thermal performance, it is
recommended that the via diameter should be 12 to 13 mils (0.30 to 0.33mm) and the via barrel should be plated
with 1 ounce copper to plug the via. This is desirable to avoid any solder wicking inside the via during the
soldering process, which may result in voids in solder between the exposed pad and the thermal land. If the
copper plating does not plug the vias, the thermal vias can be ‘tented’ with solder mask on the top surface of the
PCB to avoid solder wicking inside the via during assembly. The solder mask diameter should be at least 4 mils
(0.1mm) larger than the via diameter.
Package stand-off is also a consideration. For a nominal stand-off of 0.1mm (see Figure 27, dimension ‘A1’), the
stencil thickness of 5 to 8 mils should provide a good solder joint between the ePad and the thermal land. The
aperture opening should be subdivided into an array of smaller openings.

Figure 26. ePad Template Layout
For improved heat transfer, the exposed ePad should be soldered to the thermal land on the PCB. This requires
solder paste application not only on the pin pad pattern, but also on the thermal land using a stencil. The stencil
thickness is a function of the lead pitch, package coplanarity and stencil dimensions. For a nominal package
standoff of 0.1mm, a stencil with 5 to 8 mil thickness should provide a good solder joint between the ePad and the
thermal land.
The thermal land is covered with a passivation layer, with openings corresponding to each of the metal
rectangles. For improved solder release, the land area should be subdivided into smaller shapes, coordinated
with the pitch and size of the thermal vias. The drawing in Figure 26 is representational. Such a structure should
result in a solder joint area of 80% to 90% of the ePad area. To achieve the specified thermal performance, at
least 70% of the ePad should be soldered to the thermal land.
