HMC6545LP5 Functional Diagram

General Description

The HMC6545LP5E is a low power, high performance, fully programmable dual channel asynchronous advanced linear equalizer that operates with data rates up to 32 Gbps. The HMC6545LP5E is 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.
