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.
