Figure 2. Simplified Driver Channel
Detailed Description
The MAX9961/MAX9962 dual, low-power, high-speed,
pin electronics DCL ICs include, for each channel, a
three-level pin driver, a dual comparator, variable
clamps, and an active load. The driver features a -1.5V
to +6.5V operating range and high-speed operation,
includes high-impedance and active-termination (3rd-
level drive) modes, and is highly linear even at low volt-
age swings. The dual comparator provides low
dispersion (timing variation) over a wide variety of input
conditions. The clamps provide damping of high-speed
DUT_ waveforms when the device is configured as a
high-impedance receiver. The programmable load sup-
plies up to 2mA of source and sink current. The load
facilitates contact/continuity testing and pullup of high-
output-impedance devices.
The MAX9961A/MAX9962A provide tight matching of
offset for the drivers and the comparators allowing ref-
erence levels to be shared across multiple channels in
cost-sensitive systems. Use the MAX9961B/MAX9962B
for system designs that incorporate independent refer-
ence levels for each channel.
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 LVPECL, GTL, or other logic. Leave the inputs
unconnected for 100
differential LVDS termination.
See the Selector Guide for termination options.
The comparators provide open-collector outputs, which
must be pulled up to collector voltage VCCO. Optional
internal resistors provide 50
signal termination and
pullup without the need for external components. See
the Selector Guide for device termination options. See
the Comparators section for termination details.
A 3-wire, low-voltage, CMOS-compatible serial inter-
face programs the low-leakage, load calibration, slew
rate, and tri-state/terminate operational configurations
of the MAX9961/MAX9962.
