DUAL, QUAD, 500ps COMPARATORS ACHIEVE 30ps PROP DELAY DISPERSION
Note to Editor: These comparators set a new standard for ultra-fast propagation delay and there are no faster comparator ICs on the market.
SUNNYVALE, CA-May 31, 2002-Maxim Integrated Products introduces the MAX9600/MAX9601/MAX9602 ultra-high-speed comparators featuring propagation delay of only 500ps and edge-tracking frequency up to 4Gbps. These dual and quad comparators minimize channel-to-channel skew (10ps) and are designed for low propagation delay dispersion (30ps). These features make them ideal for applications where high-fidelity tracking of narrow pulses and low timing dispersion is critical, such as high-speed ATE, scope/logic analyzer front ends, and high-frequency line receivers with signal restoration.
The outputs are complementary digital signals, compatible with ECL or PECL systems, and provide sufficient current to directly drive transmission lines terminated at 50 . The differential input stage accepts a wide range of signals in the common-mode range from (VEE + 3V) to (VCC - 2V).
The MAX9600 and MAX9601 are dual-channel ECL and PECL output comparators incorporating a latch-enable and hysteresis control. The latch-enable control permits tracking, track-hold, or sample-hold modes of operation. Hysteresis control from 5mV to 30mV is set by an external resistor to ground and prevents oscillations due to slow-moving inputs. The MAX9602 is a quad-channel PECL output comparator ideal for high-density packaging in limited board space.
The MAX9600/MAX9601/MAX9602 are specified for operation from
-40°C to +85°C. The dual MAX9600/MAX9601 are available in 20-pin TSSOP packages with prices starting at $4.50 (1000-up, FOB USA). The quad MAX9602 comes in a 24-pin TSSOP package with prices starting at $6.75 (1000-up, FOB USA).
