DESCRIPTION

•

Individual Power-Down Controls for Both

The DS99R101/DS99R102 Chipset translates a 24-

Transmitter and Receiver

bit parallel bus into a fully transparent data/control

LVDS serial stream with embedded clock information.

•

Embedded Clock CDR (Clock and Data

This single serial stream simplifies transferring a 24-
