DESCRIPTION
TI’s Power-saver equalizer compensates for
transmission medium losses and minimizes medium-
induced deterministic jitter. Performance is
guaranteed over the full range of 5 to 12.5 Gbps. The
DS80EP100 requires no power to operate. The
equalizer operates anywhere in the data path to
minimize media-induced deterministic jitter in both
FR4 traces 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.
