Dual, Low-Power, 1200Mbps ATE
Driver/Comparator with 35mA Load
General Description
The MAX9969 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 IOH and IOL,
and pullup of high-output-impedance devices. The
MAX9969A features tighter matching of offset for the
drivers and the comparators.
The MAX9969 provides high-speed, differential control
inputs with optional internal termination resistors that
are compatible with LVPECL, LVDS, and GTL. Flexible
open-collector outputs with optional internal pullup
resistors are available for the comparators. These fea-
tures significantly reduce the discrete component count
on the circuit board.
A 3-wire, low-voltage, CMOS-compatible serial inter-
face programs the low-leakage, slew-rate limit, and tri-
state/terminate operational configurations of the
MAX9969.
The MAX9969’s operating range is -1.5V to +6.5V with
power dissipation of only 1.4W 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 +60°C to +100°C, and fea-
tures a die temperature monitor output.

*Dissipation
wattage values are based on still air with no heat sink. Actual maximum power dissipation is a function of heat extraction
technique and may be substantially higher.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
