DS32EV100
Programmable Single Equalizer
General Description
The DS32EV100 programmable equalizer provides compen-
sation for transmission medium losses and reduces the medi-
um-induced deterministic jitter for NRZ data channel. The
DS32EV100 is optimized for operation up to 3.2 Gbps for both
cables and FR4 traces. The equalizer channel has eight lev-
els 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 bal-
anced codes such as 8b/10b. The device uses differential
current-mode logic (CML) inputs and outputs. The
DS32EV100 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.
