Dual, Low-Power, 500Mbps ATE
Driver/Comparator with 35mA Load
General Description
The MAX9967 dual, low-power, high-speed, pin electron-
ics driver/comparator/load (DCL) IC includes, for each
channel, a three-level pin driver, a dual comparator, vari-
able 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 sup-
plies 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-imped-
ance devices.
The MAX9967A provides tight matching of gain and off-
set 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 tri-
state/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.
