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 programmable quad equalizer compensates for transmission‑medium losses up to 14 dB and reduces deterministic jitter on four NRZ data channels. It operates up to 3.2 Gbps on both copper cables and FR‑4 traces and offers eight levels of input equalization per channel, selectable via three control pins or an SMBus interface.
The handbook provides detailed pin descriptions, SMBus protocol information, electrical characteristics, absolute maximum ratings, and recommended operating conditions. It also includes package dimensions, power‑supply options, and typical performance figures such as power consumption, ESD rating, and temperature range.
