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 Gbps operation or
2.5 Gbps / 5.0 Gbps operation.
The DS50EV401 uses Current-mode logic (CML) on both input and output ports, which provide
constant 50 ohm single-ended impedance to AC ground. Differential signaling is implemented through
out the entire signal path to minimize supply induced jitter. The DS50EV401 is available in a 7mm x
7mm 48-pin leadless WQFN package, and is powered from a single power supply of either 3.3 or
