ABSTRACT:
A photodetector array interface circuit includes a pixel counter circuit having a plurality of sequentially numbered counters for counting pulses in a pixel oscillator signal, and a pixel counter gating circuit coupled to the pixel counter circuit for receiving both the pixel oscillator signal and a digital video signal and sequentially selecting the counters to receive the pixel oscillator signal such that the next sequential counter receives the pixel oscillator signal whenever the digital video signal changes. The interface circuit further comprises circuitry for sequentially reading the counters such that a particular counter is read only when the next sequential counter has received the pixel oscillator signal.
