DS32EV400 - National Semiconductor

DS32EV400 Programmable Single Equalizer

The DS32EV400 programmable quad equalizer provides compensation for transmission medium losses and reduces the medium-induced deterministic jitter for four NRZ data channels. The DS32EV400 is optimized for operation up to 3.2 Gbps for both cables and FR4 traces. Each equalizer channel has eight levels of input equalization that can be programmed by three con.
