General Description

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 differential input stage accepts a wide range of signals

in the common-mode range from (V

+ 3V) to (V

- 2V).

The outputs are complementary digital signals, compatible

with ECL and PECL systems, and provide sufficient current

to directly drive transmission lines terminated in 50Ω.

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.

The MAX9600/MAX9601 are available in 20-pin TSSOP

packages, and the MAX9602 is offered in a 24-pin

TSSOP package. The MAX9600/MAX9601/MAX9602

are specified for operation from -40°C to +85°C.

MAX9600/MAX9601/MAX9602 Dual ECL and Dual/Quad PECL, 500ps, Ultra-High-Speed Comparators The MAX9600/MAX9601 incorporate latch-enable and hysteresis control. Hysteresis rejects noise and prevents oscillations on low-slew input signals. The latchenable control permits tracking or sampling mode of operations. Drive the complementary latch enable with standard ECL logic for MAX9600 and PECL logic for MAX9601.

Dual ECL and Dual/Quad PECL, 500ps, Ultra-High-Speed Comparators ECL/PCL The MAX9600/MAX9601/MAX9602 outputs are emitter followers that require external resistive connections to a voltage source (VT) more negative than the lowest VOL for proper static and dynamic operation. When properly terminated, the outputs provide appropriate levels, VOL or V OH , for ECL (MAX9600) or PECL (MAX9601/ MAX9602). Output-current polarity always sinks into the termination scheme during proper operation.
