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 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 LLP 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.
