Description
The MAX9961/MAX9962 dual, low-power, high-speed,
pin electronics driver/comparator/load (DCL) ICs
include, for each channel, a three-level pin driver, a
dual comparator, variable clamps, and an active load.
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. 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 2mA of source
and sink current. The load facilitates contact/continuity
testing and pullup of high-output-impedance devices.
The MAX9961A/MAX9962A provide tight matching of
offset for the drivers and the comparators, allowing reference
levels to be shared across multiple channels in
cost-sensitive systems. Use the MAX9961B/MAX9962B
for system designs that incorporate independent reference
levels for each channel.
The MAX9961/MAX9962 provide high-speed, differential
control inputs compatible with LVPECL, LVDS, and
GTL. The MAX9961/MAX9962 are available with optional
internal termination resistors. The open-collector
comparator outputs are available with or without internal
pullup resistors. The optional internal resistors significantly
reduce the discrete component count on the
circuit board.
A 3-wire, low-voltage, CMOS-compatible serial interface
programs the low-leakage, slew-rate limit, and tri-state/
terminate operational configurations of the MAX9961/MAX9962.
The MAX9961/MAX9962s' operating range is -1.5V to
+6.5V with power dissipation of only 900mW per channel.
The devices are available in a 100-pin, 14mm x
14mm body, and 0.5mm pitch TQFP. An exposed 8mm
x 8mm die pad on the top (MAX9961) or bottom
(MAX9962) of the package facilitates efficient heat
removal. The device is specified to operate with an
internal die temperature of +70°C to +100°C, and features
a die temperature monitor output.
