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.
