Dual ECL and Dual/Quad PECL, 500ps,
Ultra-High-Speed Comparators
General Description
Features
The MAX9600/MAX9601/MAX9602 ultra-high-speed com-
parators feature extremely low propagation delay
(500ps). These dual and quad comparators minimize
propagation delay skew (10ps) and are designed for low
propagation delay dispersion (30ps). These features
make them ideal for applications where high-fidelity track-
ing of narrow pulses and low timing dispersion is critical.

The outputs are complementary digital signals, compatible
with ECL and PECL systems, and provide sufficient current
to directly drive transmission lines terminated in 50Ω.
ꢀ Adjustable Hysteresis (MAX9600/MAX9601)
The MAX9600/MAX9601 dual-channel ECL and dual-chan-
nel PECL output comparators incorporate latch enable
(LE_, LE_), and hysteresis (HYS_). The complementary
latch-enable control permits tracking, track-hold, or sample-
hold mode of operations. The latch enables can be driven
with standard ECL logic for MAX9600 and PECL logic for
MAX9601. The MAX9602 quad-channel PECL output
comparator is ideal for high-density packaging in limit-
ed board space.
