Dual Comparator/Terminator with
Cable-Droop Compensation
General Description
The MAX9955 high-speed, dual comparator/terminator
IC includes a dual comparator and a terminator for
each channel. The dual comparator features program-
mable cable-droop compensation at its input and offers
low dispersion (timing variation) over a wide variety of
input conditions, programmable hysteresis, and differ-
ential outputs. The terminator provides a 50Ω buffered
termination to a programmed level. The MAX9955 com-
parator operating range is -1.1V to +3.6V, and the ter-
minator operating range is -1.0V to +3.5V.
The MAX9955 comparator provides high-speed, open-
collector outputs with internal 50Ω termination resistors
that are compatible with doubly terminated 0.4V
P-P
(typ) CML. These features significantly reduce the dis-
crete component count on the circuit board.
The MAX9955 power dissipation is only 800mW per
channel under static conditions and 850mW per chan-
nel at 2Gbps toggling conditions. The device is avail-
able in a 64-pin, 10mm x 10mm body and 0.5mm pitch
TQFP. A 5mm x 5mm exposed die paddle on the top of
the package facilitates efficient heat removal. The
device is specified to operate with an internal die tem-
perature of +50°C to +90°C, and features a die temper-
ature monitor output.
