Detailed Description
The MAX9600/MAX9601/MAX9602 ultra-high-speed com-
parators feature extremely low propagation delay
(500ps). These dual and quad comparators minimize
channel-to-channel skew (10ps) and are designed for low
propagation delay dispersion. These features make them
ideal for applications where high-fidelity tracking of nar-
row pulses and low timing dispersion is critical. The
devices operate from either standard supply levels of
-5.2V/+5V or shifted levels of -4.2V/+6V.
The differential input stage accepts a wide range of sig-
nals in the common-mode range from (V
EE
+ 3V) to (V
CC
- 2V) with a CMRR of 70dB (typ). The outputs are com-
plementary digital signals, compatible with ECL and
PECL systems, and provide sufficient current to directly
drive transmission lines terminated in 50Ω. The ultra-fast
operation makes signal processing possible at a data
rate up to 4Gbps. Figure 2 shows a 1Gbps (500MHz)
example with an input-signal level of 100mV
