Pin Configuration
24-Pin QFN
Pin Description
Pin Number
Pin Name
Pin Function
1
FB
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.
2
VMPD
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
3
GNDA
Ground return for analog functions.
4
VDDA
Power supply input for analog functions.
5
VILD–
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.
6
VILD+
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.
7
SHDN (TXFIN)
Digital output; Programmable polarity. When used as shutdown output (SHDN), asserted
at the detection of a fault condition that can be used to activate a second series transistor
in the laser current path, enhancing protection against single-point failures. When
programmed as TXFIN, it is an input for external fault signals to be ORed with the internal
fault sources to drive TXFAULT.
8
SHDN (TXFIN)
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.
9
XPN
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.
10
TXFAULT
Digital Output; Open-Drain. A high level indicates a hardware fault impeding transmitter
operation. The state of this input is always reflected in the TXFLT bit.
