TX FAULT is an open collector output that is pulled up with a 4.7 K - 10 K W resistor on the host board. Use a pull-up voltage between 2.0 V and VccT, R+0.3 V. * Low: Indicates normal operation. In the low state, the output is pulled to < 0.8 V. * High: Indicates a laser fault. 2. TX DISABLE is an input used to shut down the transmitter optical output. It is pulled up within the TXN31111D1 Optical Transceiver with a 4.7 K - 10 K W resistor. The states are as follows: * Low (0 - 0.6 V): Transmitter Enabled * (>0.8, <2.0 V): Undefined * High (2.0 - 3.465 V): Transmitter Disabled 3. MOD-DEF 0, 1, 2: These pins are definition pins for the TXN31111D1 Optical Transceiver. They are pulled up with a 4.7 K - 10 K W resistor on the host board. Use a pull-up voltage between 2.0 V and VccT, R+0.3 V. * MOD-DEF 0 is grounded by the TXN31111D1 Optical Transceiver to indicate the TXN31111D1 Optical Transceiver is present. * MOD-DEF 1 is the clock line of a two-wire serial interface for serial ID. * MOD-DEF 2 is the data line of a two-wire serial interface for serial ID. 4. RATE SELECT: This signal function is not implemented in the TXN31111D1 Optical Transceiver. The TXN31111D1 Optical Transceiver is rate agile - that is, it meets the specifications for 1.0625 Gbps to 2.125 Gbps data rates without the use of a rate-select pin. 5. LOS (Loss of Signal) is an open collector output that is pulled up with a 4.7K - 10KW resistor on the host board. * When low, this output indicates normal operation. In the low state, the output is pulled to < 0.8V. * When high, this output indicates the received optical power is below the worst-case receiver sensitivity (as defined by the standard in use). 6. RD-/+ are the differential receiver outputs. They are AC-coupled 100 W differential lines that are terminated with 100 W (differential) at the user SerDes. The AC coupling is performed inside the TXN31111D1 Optical Transceiver and is therefore not required on the host board. 7. VccR and VccT are the receiver and transmitter power supplies. Their values, which are listed in Table 2, "Recommended Operating Conditions" on page 8, are defined at the SFP connector pin. Maximum supply current is listed in Table 3, "Electrical Characteristics - Power and Current" on page 9. Hot plugging of the TXN31111D1 Optical Transceiver results in the inrush current listed in Table 3, "Electrical Characteristics - Power and Current" on page 9. 8. TD-/+ are the differential transmitter inputs. They are AC-coupled differential lines with 100 W differential termination inside TXN31111D1 Optical Transceiver. The AC coupling is performed inside the TXN31111D1 Optical Transceiver and is therefore not required on the host board. 25-April-2007 Order Number: 317116, Revision: 001US Intel(R) TXN31111D1 Tri-Rate 850 nm Optical Transceiver - SFP* MSA Compatible Datasheet 13 Intel(R) TXN31111D1 Tri-Rate 850 nm Optical Transceiver - SFP* MSA Compatible 4.0 Termination 4.1 Types of I/O Interfaces The TXN31111D1 Optical Transceiver has the following types of I/O interfaces. * CML interface * TTL interface High-speed I/Os use the CML interface, while control signals use the TTL interface. Proper termination of I/Os is required for good signal integrity. If I/Os (particularly the CML I/Os) are not terminated properly, then jitter increases significantly due to reflection from impedance mismatches. 4.2 CML Termination Figure 2 shows a circuit diagram for the CML termination for the TXN31111D1 Optical Transceiver receiver output. The TXN31111D1 Optical Transceiver has built in ACcoupling capacitors, which help prevent a direct current path from the TXN31111D1 Optical Transceiver power supply to the SerDes input. (A direct current path could damage the ESD diodes on the SerDes.) * Internal termination. For the TXN31111D1 Optical Transceiver receiver output, the SerDes interface provides an internal termination resistor. * External termination. For the proper external termination of the SerDes interface, refer to the SerDes specification. Figure 2.

The TXN31111D1 Optical Transceiver has a digital diagnostic monitoring interface that is an extension of the serial ID interface defined in the Gigabit Interface Converter (GBIC) specification and the SFP Transceiver MultiSource Agreement (MSA) referenced in Section 1.0, "Introduction" on page 7. * Standard SFP serial ID interface. The standard SFP serial ID interface (the memory map for which is in Table 12, "Memory Map - 2-Wire Address Range Descriptions" on page 18) provides access to identification information using the 8bit address 1010000X (A0h). The serial identification information describes information such as the following for the TXN31111D1 Optical Transceiver: capabilities, standard interfaces, and manufacturer information. * Digital diagnostic monitoring interface. The digital diagnostic monitor interface (the memory map for which is in Table 12, "Memory Map - 2-Wire Address Range Descriptions" on page 18) is an extension of the standard serial ID interface. This interface, which uses the 8-bit address 1010001X (A2h) reserved for optical transceivers, allows real-time access to device-operating parameters while leaving unchanged the original serial ID memory map A0h. The digital diagnostic monitoring interface is backward compatible with both the GBIC specification and the SFP MSA.

The TXN31111D1 Optical Transceiver is referred to as a "Lead-free 2nd Level Interconnect." The enclosure, circuit board substrate, and the solder connections from the circuit board to the components (second-level connections) are all lead-free. Table 18 lists various forms of the "Lead-Free 2nd Level Interconnect" marking for the TXN31111D1 Optical Transceiver and accompanying collateral. Table 18. Lead-Free 2nd-Level Interconnect Markings Description Marking Lead-Free 2nd Level Interconnect: The Lead-Free 2nd Level Interconnect symbol is used to identify electrical and electronic assemblies and components in which the lead (Pb) concentration level in the circuit board substrate and the solder connections from the circuit board to the components (second-level interconnect) are not greater than 0.1% by weight (1000 ppm). Note: 8.4 Any of the three symbols shown may be used, as space permits. or or Compliance with Restriction of Hazardous Substances (RoHS) This product complies with the European Union directive for Restriction of Hazardous Substances (RoHS) - Restriction on the Use of Certain Hazardous Substances in Electrical and Electronic Equipment, Directive 2002/95/EC plus amendments. However, certain discrete components do contain lead (an RoHS-restricted substance) in amounts that exceed threshold concentration levels. This product uses the following applicable RoHS technology exemptions: * Lead in optical and filter glass * Lead in glass of electronic components Note: RoHS implementation details are subject to change. This product is RoHS 6 compliant, defined as complying with the restriction for all six listed substances by meeting strict threshold levels for those substances or through the use of the applicable exemptions listed above. 25-April-2007 Order Number: 317116, Revision: 001US Intel(R) TXN31111D1 Tri-Rate 850 nm Optical Transceiver - SFP* MSA Compatible Datasheet 25 Intel(R) TXN31111D1 Tri-Rate 850 nm Optical Transceiver - SFP* MSA Compatible 8.5 Management Methods on Control of Pollution from Electronic Information Products (a.k.a.
