HmC750lp4e is a limiting amplifier designed to sup-

port data transmission rates up to 12.5 gbps. the

amplifier can operate over a wide range of input voltage

levels and provides constant-level differential output

swing. HmC750lp4e also features an output level

control pin, VC1, which allows for loss compensation

or for signal level optimization. Differential output

signal swing can be adjustable up to 880 mVp-p.

input signals higher than 3mV p-p can be amplified to

saturated 880mV p-p differential signal.

all single-ended input signals to the HmC750lp4e

are terminated with 50 ohms to +5V on-chip, and

may be either aC or DC coupled. the outputs of the

HmC750lp4e may be operated either differentially

or single-ended. Outputs can be connected directly

to a 50 ohm terminated system referenced to +5V,

while DC blocking capacitors may be used if the

terminating system is 50 ohms to a non +5V voltage.

the HmC750lp4e operates from a single + 5V DC

supply and is available in a plastic roHs compliant

4x4 mm smt package.
