DESCRIPTION
National’s Power-saver equalizer compensates for
transmission medium losses and minimizes medium-
induced deterministic jitter. Performance is
guaranteed over the full range of 1 to 5 Gbps. The
DS38EP100 requires no power to operate. The
equalizer operates anywhere in the data path to
minimize media-induced deterministic jitter in both
FR4 and cable applications. Symmetric I/O structures
support full duplex or half duplex applications. Linear
compensation is provided independent of line coding
or protocol. The device is ideal for both bi-level and
multi-level signaling.
The equalizer is available in a 6 pin leadless WSON
package with a space saving 2.2 mm X 2.5 mm
footprint. This tiny package provides maximum
flexibility in placement and routing of the Power-saver
equalizer.
