s0297. rev.01. (web) 2012-04-05 4 tpp4xgflrxg oplink communications, inc electrical interface: all signal interfaces are compliant with the sfp+ msa specifcation. the high speed data interface is differential ac-coupled internally and can be directly connected to a 3.3v serdes ic. all low speed control and sense output signals are open collector ttl compatible and should be pulled up with a 4.7 k - 10 k resistor on the host board. loss of signal (los): the loss of signal circuit monitors the level of the incoming optical signal and generates logic high when an insufcient photocurrent is produced. tx_fault: the output indicates low when the transmitter is operating normally and high with a laser fault including laser end-of-life. tx fault is an open collector/drain output and should be pulled up with a 4.7 k - 10 k resistor on the host board. tx_disable: when the tx disable pin is at logic high, the transmitter optical output is disabled. the laser is also disabled if this line is left foating, as it is pulled high inside the transceiver. serial identification and monitoring: the module defnition of sfp is indicated by the mod_abs pin and the 2-wrie serial interface. upon power up, the 2-wrie interface appears as nc (no connection), and mod_abs is ttl low. when the host system detects this condition, it activates the serial protocol (standard two-wire i 2 c serial interface) and generates the serial clock signal (scl). the positive edge clocks data into the eeprom segments of the device that are not write protected, and the negative edge clocks data from the device. the serial data signal (sda) is for serial data transfer. the host uses sda in conjunction with scl to mark the start and end of serial protocol activation. the supported monitoring functions are temperature, voltage, bias current, transmitter power, average receiver signal, all alarms and warnings, and software monitoring of tx fault/los. the device is internally calibrated. the data transfer protocol and the details of the mandatory and vendor specifc data structures are defned in the sfp msa, and sff-8472, rev. 10.4. power supply and grounding: the power supply line should be well-fltered. all power supply bypass capacitors should be as close to the transceiver module as possible. application notes module pin description pin logic symbol description 1 - veet module transmitter ground 2 lvttl-o tx_fault module transmitter fault 3 lvttl-i tx_disable transmitter disable; turns of transmitter laser output 4 lvttl-i/o sda 2-wire serial interface data line 5 lvttl-i/o scl 2-wire serial interface clock 6 - mod-abs module defnition, grounded in the module 7 lvttl-i rs0 no function implemented 8 lvttl-o rx_los receiver loss of signal indication 9 lvttl-i rs1 no function implemented 10 - veer module receiver ground 11 - veer module receiver ground 12 cml-o rd- receiver inverted data output 13 cml-o rd+ receiver non-inverted data output 14 - veer module receiver ground 15 - vccr module receiver 3.3v supply 16 - vcct module transmitter 3.3v supply 17 - veet module transmitter ground 18 cml-i td+ transmitter non-inverted data input 19 cml-i td- transmitter inverted data input 20 - veet module transmitter ground
