DS38EP100
1 to 5 Gbps, Power-Saver Equalizer for Backplanes and
Cables
General Description
National’s Power-saver equalizer compensates for transmis-
sion medium losses and minimizes medium-induced deter-
ministic 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 ap-
plications. Symmetric I/O structures support full duplex or half
duplex applications. Linear compensation is provided inde-
pendent 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 rout-
ing of the Power-saver equalizer.
