Programmable Quad Equalizer 48-Pin LLP EP T/R

The DS64EV400 programmable quad equalizer provides compensation for transmission medium losses and reduces the medium-induced deterministic jitter for four NRZ data channels. The DS64EV400 is optimized for operation up to 10 Gbps for both cables and FR4 traces. Each equalizer channel has eight levels of input equalization that can be programmed by three control pins, or individually through a Serial Management Bus (SMBus) interface.The equalizer supports both AC and DC-coupled data paths for long run length data patterns such as PRBS-31, and balanced codes such as 8b/10b. The device uses differential current-mode logic (CML) inputs and outputs. The DS64EV400 is available in a 7 mm x 7 mm 48-pin leadless WQFN package. Power is supplied from either a 2.5V or 3.3V supply.
