DESCRIPTION
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.
