VeeT Transmitter Ground. VeeT and VeeR are internally con- nected within the AFCT-57V6USZ module. VeeR Receiver Ground. VeeT and VeeR are internally con- nected within the AFCT-57V6USZ module. VccT Transmitter +3.3 V Power Supply. VccT and VccR are internally connected within the AFCT-57V6USZ module. VccR Receiver +3.3V Power Supply. VccT and VccR are internally connected within the AFCT-57V6USZ module. TD+/TD- Transmit Data In and Inverted Transmit Data In are differential input to the transmitter. They are internally AC-coupled into an equivalent load of RI differential, as shown in Figure 13. TX_DISABLE Active high TTL input, with internal 9.4k ohm pull-up resistor to Vcc. Asserting the transmitter disable will deactivate the laser within the assert time. The truth table shown describes the state of the module, and Table 11 indicates the timing of TX_DISABLE. RD+/RD- Received Data Out and Inverted Received Data Out are differential serial output from the receiver. These are AC-coupled 100 ohm differential lines which should be terminated with a 100 ohm (differential) at the user SERDES, as shown in Figure 13. AC coupling is done inside the module and is thus not required on the host board. RX_LOS Active high open collector/drain output which indicates a loss-of-signal condition (LOS). When the aver- age optical power received by the module is below the Assert Level, RX_LOS is indicated according to the truth table below, and Table 11 indicates the timing of RX_LOS. RX_LOS requires a 4.7k-10k ohm pull-up resistor external to the module, i.e., in the host system Host_Vcc, as shown in Figure 13. The pull-up voltage is between 2.0 V and VccR(VccT) + 0.3 V. RATE_SELECT Not Connected. TX_FAULT Active high open collector/drain output which indicates a fault in the module. This can be (1) failure of the laser driver or (2) end-of-life of the laser. Under these conditions, the laser will be de- activated within the assert time. TX_FAULT also requires a 4.7k-10k ohm pull-up resistor external to the module, i.e. in the host system Host_Vcc, as shown in Figure 13. The pull-up voltage is between 2.0 V and VccT(VccR) + 0.3 V. Conditions (1) and (2) are latched, and for diagnostic pur- poses only, may be reset by toggling TX_DISABLE high for at least t_reset. See Table 11 and Figure 8. MOD_DEF[0:2] The AFCT-57V6USZ has a serial ID func - tion which provides information about the transceiver’s capabilities, standard interfaces, manufacturer and other information, and has a digital diagnostic monitoring function, per SFF-8472 [3], which allows monitoring op - erating temperature, supply voltage, laser bias current, transmitter optical output power and optical received power in real time. These functions are provided via a two wire serial EEPROM interface. MOD_DEF[0] is connected to ground inside the module. MOD_DEF[1] is the serial clock signal input. MOD_DEF[2] is the data output/input.
