The MAX9969 dual, low-power, high-speed, pin elec-
tronics DCL IC includes, for each channel, a three-level
pin driver, a dual comparator, variable clamps, and an
active load. An additional differential comparator allows
comparisons between the two channels. The driver fea-
tures a -1.5V to +6.5V operating range and high-speed
operation, includes high-impedance and active-termi-
nation (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 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 test of IOH and IOL, and
pullup of high-output-impedance devices. The
MAX9969A features tighter matching of offset for the
drivers and the comparators.
Optional internal resistors at the high-speed inputs pro-
vide compatibility with LVPECL, LVDS, and GTL inter-
faces. Connect the termination voltage inputs (TDATA_,
TRCV_, TLDEN_) to the appropriate voltage for termi-
nating LV_PECL, GTL, or other logic. Leave the inputs

unconnected for 100Ω differential LVDS termination. In
addition, flexible open-collector outputs with optional
internal pullup resistors are available for the compara-
tors. 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, load-disable, slew-rate, dif-
ferential/window comparator and tri-state/terminate
operational configurations of the MAX9969.
The driver input is a high-speed multiplexer that selects
one of three voltage inputs: DHV_, DLV_, or DTV_. This
switching is controlled by high-speed inputs DATA_
and RCV_ and mode-control bit TMSEL (Table 1). A
slew-rate circuit controls the slew rate of the buffer
input. Select to one of four possible slew rates accord-
ing to Table 2. The speed of the internal multiplexer
sets the 100% driver slew rate (see the Driver Large-
Signal Response graph in the Typical Operating
Characteristics).
DUT_ can be toggled at high speed between the buffer
output and high-impedance mode, or it can be placed
into low-leakage mode (Figure 2, Table 1). In high-
impedance mode, the clamps are connected. High-
