DESCRIPTION
The DS32EV400 programmable quad equalizer
provides compensation for transmission medium
losses and reduces the medium-induced deterministic
jitter for four NRZ data channels. The DS32EV400 is
optimized for operation up to 3.2 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 device equalizes up to 14 dB of loss at 3.2 Gbps.
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.
Each channel has an independent signal detect
output and independent enable input. The SD output
maybe tied to the EN to automatically control the
power up and down of the channel.
The DS32EV400 can be used in a variety of
applications that include DisplayPort, XAUI,
InfiniBand and other high-speed data transmission
applications.
The DS32EV400 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.
