The MAX9967 dual, low-power, high-speed, pin electronics
driver/comparator/load (DCL) IC includes, 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-undertest
(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 MAX9967A provides tight matching of gain and offset
for the drivers, and offset for the comparators and
active load, allowing reference levels to be shared
across multiple channels in cost-sensitive systems. Use
the MAX9967B for system designs that incorporate
independent reference levels for each channel.
The MAX9967 provides high-speed, differential control
inputs with optional internal termination resistors that
are compatible with ECL, LVPECL, LVDS, and GTL.
ECL/LVPECL or flexible open-collector outputs with
optional internal pullup resistors are available for the
comparators. 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, slew-rate limit, and tristate/
terminate operational configurations of the
MAX9967.
The MAX9967's operating range is -1.5V to +6.5V with
power dissipation of only 1.15W per channel. The
device is available in a 100-pin, 14mm x 14mm 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 +70°C to +100°C, and
features a die temperature monitor output.
