General Description

The MAX9963/MAX9964 four-channel, low-power, high speed pin electronics driver and comparator ICs include, for each channel, a three-level pin driver, a dual comparator, and variable clamps. The driver features a wide voltage range and high-speed operation, includes high-Z and active-termination (3rd-level drive) modes, and is highly linear even at low-voltage swings. The dual comparator provides low dispersion (timing variation) over a wide variety of input conditions. The clamps provide damping of high-speed DUT waveforms when the device is configured as a high-impedance receiver. High-speed, differential control inputs compatible with ECL, LVPECL, LVDS, and GTL levels are provided for each channel. ECL/LVPECL or flexible open-collector outputs are available for the comparators.
