DESCRIPTION
The DS64EV100 programmable equalizer provides compensation for transmission medium losses and reduces
the medium-induced deterministic jitter for NRZ data channel. The DS64EV100 is optimized for operation up to
10 Gbps for both cables and FR4 traces. The equalizer channel has eight levels of input equalization that can be
programmed by three control pins.
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 DS64EV100 is available in a 3 mm x 4 mm 14-pin leadless LLP package. Power is supplied from either a
2.5V or 3.3V supply.
