The ADCMP563/ADCMP564 are high speed comparators fabricated on Analog Devices’ proprietary XFCB process. The devices feature a 700 ps propagation delay with less than 75 ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of high speed comparators. A separate programmable hysteresis pin is available on the ADCMP564. A differential input stage permits consistent propagation delay with a wide variety of signals in the common-mode range from −2.0 V to +3.0 V. Outputs are complementary digital signals that are fully compatible with ECL 10 K and 10 KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 Ω to −2 V. A latch input, which is included, permits tracking, track-and-hold, or sample-and-hold modes of operation. The latch input pins contain internal pull-ups that set the latch in tracking mode when left open. The ADCMP563/ADCMP564 are specified over the industrial temperature range (−40°C to +85°C).
