Dual, Low-Power, 1200Mbps ATE
Driver/Comparator with 35mA Load
General Description
The MAX9975 dual, low-power, high-speed, pin elec-
tronics driver/comparator with 35mA load IC includes,
for each channel, a three-level pin driver, a dual com-
parator, variable clamps, and an active load. An addi-
tional differential comparator allows comparisons
between the two channels. The driver features a wide
voltage range and high-speed operation, includes high-
impedance 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 I_OH and I_OL, and
pullup of high-output-impedance devices.
The MAX9975 provides high-speed, differential control
inputs and open-collector outputs with internal 50Ω ter-
mination 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 inter-
face programs the low-leakage and tri-state/terminate
operational configurations of the MAX9975.
The MAX9975ARCCQ operating range is -1.5V to +6.5V.
The MAX9975AZCCQ operating range is -1.0V to +7.0V.
The MAX9975 features power dissipation of only 1.6W
per channel. The device is available in a 100-pin, 14mm
x 14mm x 0.1mm body, and 0.5mm pitch TQFP. An
exposed 8mm x 8mm die pad on the top of the package
facilitates efficient heat removal. The device is specified
to operate with an internal die temperature of +60°C to
+100°C, and features a die temperature monitor output.
