DS32EV100 Programmable Single Equalizer November 5, 2007 DS32EV100 Programmable Single Equalizer General Description The DS32EV100 programmable equalizer provides compensation for transmission medium losses and reduces the medium-induced deterministic jitter for NRZ data channel. The DS32EV100 is optimized for operation up to 3.2 Gbps for both cables and FR4 traces. The equalizer channel has eight levels of input equalization that can be programmed by three control pins. www.DataSheet4U.com 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.
