The HMC6545LP5E is a low power, high performance,
fully programmable dual channel asynchronous advanced
linear equalizer operating with data rates up to 32 Gbps.
The HMC6545LP5E is a protocol and data rate agnostic and
it can operate on the transmit path to pre-distort transmitted
signal in order to invert channel distortion or on the receiver
path to equalize the distorted and attenuated received signal.
The HMC6545LP5E is effective in dealing with chromatic and
polarization mode dispersion and inter-symbol interference (ISI)
caused by wide variety of transmission media, backplane and
or fiber, and channel lengths. HMC6545LP5E complements
CTLE / DFE based ASIC’s in effectively dealing with reflections,
crosstalk and ISI related issues.
The low power, high performance and feature rich HMC6545LP5E
is packaged in a 5 x 5 mm 32 pin QFN package. The device
uses a single 3.3V supply eliminating external regulators. The
HMC6545LP5E operates over a case temperature range of
-40° C up to 95° C.
