DESCRIPTION
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 2 C Serial Data I/O
I 2 C Serial Clock Input
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 2 C interface. Alarm and warning values can be assigned to interrupt the
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.
Monitor Diode Input (Feedback Voltage, Transmit Power Monitor)
Power Supply Input
