Burst Enable Input. Triggers the sampling of the APC and Quick-trip monitors.
Transmit Disable Input. Disables BIAS and MOD outputs.
No Connection
Transmit Fault Output. Open-drain.
Output to FET Gate. Signals an external N or P Channel MOSFET to enable/disable the laser’s current.

I
Ground
External Analog Inputs. The voltage at these pins is digitized by the internal analog-to-digital converter
and can be read through the I
processor based on the ADC result.
Ground
Bias Current Output. This current DAC generates the bias current reference for the MAX3643.
Modulation Output Voltage. This 8-bit voltage output has 8 full-scale ranges from 1.25V to 0.3125V.
This pin is connected to the MAX3643’s VMSET input to control the modulation current.
