DS64EV100 Programmable Single Equalizer www.DataSheet4U.com November 9, 2007 DS64EV100 Programmable Single Equalizer General Description The DS64EV100 programmable equalizer provides compensation for transmission medium losses and reduces the medium-induced deterministic jitter for NRZ data channel. The DS64EV100 is optimized for operation up to 10 Gbps for both cables and FR4 traces. The equalizer channel has eight levels of input equalization that can be programmed by three control pins. 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, and is available in a 3 mm x 4 mm 14-pin leadless LLP package. Power is supplied from either a 2.5V or 3.3V supply.
