MAX9600/MAX9601/MAX9602 19-2409 Rev 1 9/02 Dual ECL and Dual/Quad PECL, 500ps, Ultra-High-Speed Comparators General Description Features The MAX9600/MAX9601/MAX9602 ultra-high-speed com- 500ps Propagation Delay parators feature extremely low propagation delay 30ps Propagation Delay Dispersion (500ps). These dual and quad comparators minimize 4Gbps Tracking Frequency propagation delay skew (10ps) and are designed for low propagation delay dispersion (30ps). These features -2.2V to +3V Input Range with +5V/-5.2V Supplies make them ideal for applications where high-fidelity track- -1.2V to +4V Input Range with +6V/-4.2V Supplies ing of narrow pulses and low timing dispersion is critical. Differential ECL Outputs (MAX9600) The differential input stage accepts a wide range of signals Differential PECL Outputs (MAX9601/MAX9602) in the common-mode range from (V + 3V) to (V - 2V). EE CC The outputs are complementary digital signals, compatible Latch Enable (MAX9600/MAX9601) with ECL and PECL systems, and provide sufficient current Adjustable Hysteresis (MAX9600/MAX9601) to directly drive transmission lines terminated in 50 . The MAX9600/MAX9601 dual-channel ECL and dual-chan- Ordering Information nel PECL output comparators incorporate latch enable (LE , LE ), and hysteresis (HYS ).

The latch enables can be driven MAX9601EUP -40C to +85C 20 TSSOP with standard ECL logic for MAX9600 and PECL logic for MAX9601. The MAX9602 quad-channel PECL output MAX9602EUG -40C to +85C 24 TSSOP comparator is ideal for high-density packaging in limit- ed board space. Selector Guide The MAX9600/MAX9601 are available in 20-pin TSSOP packages, and the MAX9602 is offered in a 24-pin PART PIN-PACKAGE SELECTION TSSOP package. The MAX9600/MAX9601/MAX9602 Dual ECL Output are specified for operation from -40C to +85C.
