DS50EV401 - National Semiconductor

DS50EV401 2.5Gbps / 5.0Gbps or 8.0Gbps Quad Cable and Backplane Equalizer

The DS50EV401 is a low power, programmable equalizer specifically designed to reduce inter-symbol interference (ISI) induced by a variety of interconnect media. In all modes, the equalizer can operate, error free, with an input eye that is completely closed by interconnect ISI. The MODE control, allows the user to select between equalization settings for 8.0.
