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. APPLICATIONS 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. QSFP+ direct attach active copper modules 10 Gb, 40 Gb Ethernet and OTN line cards 10 Gb, 40 Gb backplane drivers 8 Gb, 16 Gb Fibre Channel and InfiniBand® EDR line cards and backplane drivers The HMC7545 is packaged in a 36-lead, 4 mm × 7 mm LFCSP package and operates from −40°C to +85°C.
