MAX9975

19-0242; Rev 0; 6/05 Dual, Low-Power, 1200Mbps ATE Driver/Comparator with 35mA Load General Description The MAX9975 dual, low-power, high-speed, pin electronics driver/comparator with 35mA load IC includes, for each channel, a three-level pin driver, a dual comparator, variable clamps, and an active load. An additional differential comparator allows comparisons between the two channels. The driver features a wide voltage range and high-speed operation, includes highimpedance 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, and differential outputs. The clamps provide damping of high-speed device-under-test (DUT) waveforms when the device is configured as a high-impedance receiver. The programmable load supplies up to 35mA of source and sink current. The load facilitates contact/continuity testing, at-speed parametric testing of IOH and IOL, and pullup of high-output-impedance devices. The MAX9975 provides high-speed, differential control inputs and open-collector outputs with internal 50Ω termination resistors that make it CML compatible. These features significantly reduce the discrete component count on the circuit board. A 3-wire, low-voltage, CMOS-compatible serial interface programs the low-leakage and tri-state/terminate operational configurations of the MAX9975. The MAX9975ARCCQ operating range is -1.5V to +6.5V.
