The Enable pin is used to enable/disable the output. When the Enable pin is connected to ground, the
output is disabled. When this pin is connected to VCC or left open, the laser current is enabled, allowing
current to flow through the laser diode.
The current is set by the voltage at the current control input. The voltage, on the current control input,
programs the laser diode drive current, IOUT. When the input is at GND the modulation current is zero.
Maximum laser current occurs when this voltage is VCC.
Ground return for VCC (input power supply).
This high impedance input is used with a photodetector to control Output Current.
At VCC this input disables Feedback on Pin 3, which allows diode current to be set by Pin 6.
This Output provides drive current to the laser diode; (anode/positive; connect cathode to ground). Maxi-
mum drive current is dependent upon laser diode impedance and power supply input voltage.
The optical monitor voltage is proportional to the optical output power of the laser diode as sensed by a
backfacet photodetector over the range of 1µA to 1mA.
