Dual High Speed ECL Comparator 20 - Lead QSOP
The ADCMP563/ADCMP564 are high speed comparators fabricated on Analog Devices’ proprietary XFCB process. The devices feature a 1 ns propagation delay with less than 150 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 . to -2 V. A latch input, which is included, permits tracking, track-and-hold, or sample-and-hold modes of operation.
The ADCMP563/ADCMP564 are specified over the industrial temperature range (-40°C to +85°C). The ADCMP563 is available in a 16-lead QSOP package. The ADCMP564 is available in a 20-lead QSOP package.Applications
