The ADCMP562BRQZ is a dual high speed PECL Comparator fabricated on proprietary XFCB process. The device features a 700ps propagation delay with less than 75ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of comparators. A differential input stage permits consistent propagation delay with a wide variety of signals in the common-mode range from -2 to 3V. Outputs are complementary digital signals that are fully compatible with PECL 10K and 10KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50R to VDD to 2V.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.
