Sinks or sources the bias current for the laser in both APC and open loop modes.
Compensation pin used to control the bandwidth of the APC loop. Connect a 0.01-µF
capacitor to ground.

Circuit ground.
Transmitter and receiver loss of lock indicator. High level indicates the transmitter or
the receiver is out of lock. Open drain output. Requires an external 4.7 kΩ to 10 kΩ
pull-up resistor to VCC for proper operation. This pin is 3.3 V tolerant.

Bias current monitor.
Photodiode current monitor.
Photodiode input. Pin can source or sink current dependent on register setting.
Disables the receiver output buffer when set to a high level. Includes a 250-kΩ pull-
up resistor to VCC. Ground the pin to enable the output. This is an ORed function
with the RXOUT_DIS bit (bit 6 in register 4). This pin is 3.3-V tolerant.

Receiver loop filter capacitor.
Receiver loss of signal. High level indicates that the receiver input signal amplitude is
below the programmed threshold level. Open drain output. Requires an external 4.7-
kΩ to 10-kΩ pull-up resistor to VCC for proper operation. This pin is 3.3-V tolerant.
