TX FAULT is an open collector/drain output that is pulled up with a 4.7 K - 10 K 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 TXN31111 Optical Transceiver with a 4.7K - 10K resistor. The states are as follows: * Low (0 - 0.6V): Transmitter Enabled * (>0.8, <2.0V): Undefined * High (2.0 - 3.465V): Transmitter Disabled 3. MOD-DEF 0,1,2: These pins are the definition pins for the TXN31111 Optical Transceiver. They are pulled up with 4.7K - 10K resistor on the host board. Use a pull-up voltage between 2.0V and VccT, R + 0.3V. * MOD-DEF 0 is grounded by the TXN31111 Optical Transceiver to indicate the TXN31111 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 not implemented in the TXN31111 Optical Transceiver. The TXN31111 Optical Transceiver is rate agile - that is, it meets the specifications for 1.0625 Gbps to 2.5 Gbps data rates without the use of a rate-select pin. 5. LOS (Loss of Signal) has an internal 8K pull-up resistor to VccR. While LOS is defined per the SFP MSA, * 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 differential lines that are terminated with 100 (differential) at the user SerDes. The AC coupling is performed inside the TXN31111 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 7, are defined at the SFP connector pin. Maximum supply current is listed in Table 3, "Electrical Characteristics" on page 8. Hot plugging of the TXN31111 Optical Transceiver result in the inrush current listed in Table 3, "Electrical Characteristics" on page 8. 8. TD-/+: are the differential transmitter inputs. They are AC-coupled differential lines with 100 differential termination inside the TXN31111 Optical Transceiver. The AC coupling is done inside the TXN31111 Optical Transceiver and is therefore not required on the host board.

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. 20-Sept-2006 14 Intel(R) TXN31111 Tri-Rate 850 nm Optical Transceiver Order Number: 280049, Revision: 006 Datasheet Intel(R) TXN31111 Tri-Rate 850 nm Optical Transceiver 4.2 CML Termination Figure 2 shows a circuit diagram for the CML termination for the TXN31111 Optical Transceiver receiver output. The TXN31111 Optical Transceiver has built in AC-coupling capacitors, which help prevent a direct current path from the TXN31111 Optical Transceiver power supply to the SerDes input. (A direct current path could damage the ESD diodes on the SerDes.) * Internal termination. For the TXN31111 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.
