14.2 Gbps Asynchronous 4-Channel Signal Conditioner

The HMC7545 is a unidirectional, quad-channel, protocol and data rate agnostic, asynchronous signal conditioner, designed for short and intermediate range optical modules, line cards, and backplane applications operating at up to 14.2 Gbps.

Each channel provides programmable input equalization, LOS and receiver detection, automatic output squelch, programmable output swing and output de-emphasis.

All high speed differential inputs and outputs of the HMC7545 are current mode logic (CML), terminated on-chip with 50 Ω to the positive supply, and can be dc-coupled or ac-coupled.

The device uses a single supply, 2.5 V or 3.5 V, and its typical power dissipation is less than 80 mW per channel.

The HMC7545 is packaged in a 36-lead, 4 mm × 7 mm LFCSP package and operates from -40°C to +85°C.
