The DS64EV400 is a programmable quad equalizer that provides compensation for transmission medium losses and reduces the medium-induced deterministic jitter for four NRZ data channels.
The DS64EV400 programmable quad equalizer provides compensation for transmission‑medium losses and reduces deterministic jitter for four NRZ data channels. It operates up to 10 Gbps on cables or FR4 traces and offers eight levels of programmable equalization per channel, selectable via control pins or an SMBus interface.
The document includes a general description, pin descriptions, SMBus control details, ordering information, absolute maximum ratings, electrical characteristics, signal‑detect timing, physical dimensions, and notes on usage and warranty.
