DESCRIPTION
TI’s Power-saver equalizer compensates for
transmission medium losses and minimizes medium-
induced deterministic jitter. Performance is ensured
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.
