ADCMP551BRQZ Datasheet PDF - ADI

●The ADCMP551BRQZ is a single-supply high speed PECL/LVPECL Comparator fabricated on proprietary XFCB process. The device features a 500ps propagation delay with less than 125ps overdrive dispersion. Overdrive dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of high speed comparators. A differential input stage permits consistent propagation delay with a common-mode range from -0.2V to VCCI to 2V. Outputs are complementary digital signals and are fully compatible with PECL and 3.3V LVPECL logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50R to VCCO to 2V. A latch input is included and 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.
