Pin Function
Analog Input. Feedback voltage for the APC loop op-amp. Polarity and scale are programmable
via the APC configuration bits. Connect to VBIAS if APC is not used.
Analog Input. Multiplexed A/D converter input for monitoring transmitted optical power via a
monitor photodiode. In most applications, VMPD will be connected directly to FB. The input range
is 0 - VREF or 0 - VREF/4 depending on the setting of the APC configuration bits
Ground return for analog functions.
Power supply input for analog functions.
Analog Input. Reference terminal for the multiplexed pseudo-differential A/D converter inputs for
monitoring laser bias current via a sense resistor (VILD+ is the sensing input). Tie to VDD or GND
to reference the voltage sensed on VILD+ to VDD or GND, respectively. Limited common-mode
voltage range, see “Applications Information” section for more details.
Analog Input. Multiplexed A/D input for monitoring laser bias current via a sense resistor (signal
input); accommodates inputs referenced to VDD or GND (see pin 5 description). Limited common-
mode voltage range, see “Applications Information” section for more details.
Digital output/Input; programmable polarity. When used as shutdown output (SHDN), OEMCFG3-2
set to 0, SHDN is asserted at the detection of a fault condition if OEMCFG4-7 is set to 0. If the
latter bit is set to 1, a fault condition will not assert SHDN. When programmed as TXFIN, it is an
input for external fault signals to be ORed with the internal fault sources to drive TXFAULT.
Analog Input. Multiplexed A/D converter input for monitoring received optical power. The input
range is 0 to VREF. A 5-bit programmable EEPOT on this pin provides for coarse calibration and
ranging of the RX power measurement.
Analog Input/Output. Optional connection to an external PN junction for sensing temperature at a
remote location. The Zone bit in OEMCFG1 determines whether temperature is measured using
the on-chip sensor or the remote PN junction.
Digital Output; Open-Drain, programmable polarity. If OEMCFG5-4 is set to 0, a high level
indicates a hardware fault impeding transmitter operation. The state of this pin is always reflected
in the TXFLT bit.
