This document describes the features and characteristics of the ADCMP563/ADCMP564 dual high speed ECL comparators, including differential ECL-compatible outputs, 700ps propagation delay, input common-mode range, robust input protection, programmable hysteresis, etc.
The ADCMP563 and ADCMP564 are high-speed comparators fabricated on Analog Devices' proprietary XFCB process. They feature a 700 ps propagation delay with less than 75 ps overdrive dispersion and are compatible with ECL 10 K and 10 KH logic families. The devices include a differential input stage and a programmable hysteresis pin on the ADCMP564 model.
