Ultra-high-speed Phase Discriminator Has no Dead Zone

AD9901 Digital Detector Has Low Noise, Linear Transfer Function; ECL/TTL/CMOS-Compatible for Telecommunications, Synthesis

The AD9901 Digital Phase/Frequency Discriminator (detector) is a monilithic IC that directly compares two inputs, then produces a train of output pulses with duty cycle proportional to the phase difference. It will handle signals of any frequency—to well beyond 100 MHz. Read full article
