The ADCMP553BRMZ is a High Speed PECL/LVPECL Comparator fabricated on proprietary XFCB process. It 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 comparator. A differential input stage permits consistent propagation delay with a common-mode range from -0.2V to VCCI -2.0V. 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 -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.
