The DS64EV400 programmable quad equalizer provides compensation for transmission medium
losses and reduces the medium-induced deterministic jitter for four NRZ data channels. The
DS64EV400 is optimized for operation up to 10 Gbps for both cables and FR4 traces. Each equalizer
channel has eight levels of input equalization that can be programmed by three control pins, or
individually through a Serial Management Bus (SMBus) interface.
The equalizer supports both AC and DC-coupled data paths for long run length data
patterns such as PRBS-31, and balanced codes such as 8b/10b. The device uses differential
current-mode logic (CML) inputs and outputs. The DS64EV400 is available in a 7 mm x 7 mm 48-pin
leadless WQFN package. Power is supplied from either a 2.5V or 3.3V supply.
