2.5V V_DD)
DESCRIPTION
The DS50EV401 is a low power, programmable
equalizer specifically designed to reduce inter-symbol
interference (ISI) induced by a variety of interconnect
media. In all modes, the equalizer can operate, error
free, with an input eye that is completely closed by
interconnect ISI. The MODE control, allows the user
to select between equalization settings for 8.0 Gbps
operation or 2.5 Gbps / 5.0 Gbps operation.
The DS50EV401 uses Current-mode logic (CML) on
both input and output ports, which provide constant
50 ohm single-ended impedance to AC ground.
Differential signaling is implemented through out the
entire signal path to minimize supply induced jitter.
The DS50EV401 is available in a 7mm x 7mm 48-pin
leadless WQFN package, and is powered from a
single power supply of either 3.3 or 2.5V.
