Functional Diagram
General Description
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.
