It comes with a high stability low noise 2.5V voltage reference output which can be used for setting the output current. The reference output can also be used for the ADCs (Analog to Digital Converters) and/or DACs (Digital to Analog Converters) to monitor the laser output current and/or set laser output current respectively.
The frequency synchronization of this laser driver allows using an external digital signal to synchronize the internal PWM output stage of the laser driver, to eliminate frequency beating interferences between the laser drivers and other switch mode electronic circuits on the same PCB.
