PD200T User Guide

Quickstart

1. Supply +VCC pin with a voltage between 3.7 V and 12 V. The board is regulated to 3.3 V internally. Using more than 3.7 V supplies increases power consumption without any significant improvement in supply noise rejection.

2. Supply the photodetector with a maximum 2 mW optical power.

3. The analog output is available on the SMA connector PD out (50 Ω impedance). The TTL output is available on the SMA connector TTL out (50 Ω impedance).

   Adjust the detection threshold with the potentiometer (blue). The threshold can be monitored on the MON pin.
