General Description
HMC914LP4E is a limiting amplifier designed to
support 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. HMC914LP4E features a loss of signal
(LOS) indicator output where the input signal amplitude
threshold level can be adjusted using the LOSTH pin.
HMC914LP4E also features an output level control
pin, VAC, which allows for loss compensation or for
output signal level optimization. Differential output
signal swing can be adjusted up to 750 mVp-p. An
integrated DC offset compensation is also provided
on chip. The HMC914LP4E provides an analog RSSI
output voltage which is proportional to input signal
amplitude.
All single-ended input signals are terminated with
50 ohms to +3.3V on-chip, and may be either AC or
DC coupled. The outputs of the HMC914LP4E may
be operated either differentially or single-ended. The
HMC914LP4E operates from a single +3.3V DC supply
and is available in a plastic RoHS compliant 4x4 mm
SMT package.
