Description

The DS99R101/DS99R102 Chipset translates a 24-bit parallel bus into a fully transparent data/control LVDS serial stream with embedded clock information. This single serial stream simplifies transferring a 24-bit bus over PCB traces and cable by eliminating the skew problems between parallel data and clock paths. It saves system cost by narrowing data paths that in turn reduce PCB layers, cable width, and connector size and pins.

The DS99R101/DS99R102 incorporates LVDS signaling on the high-speed I/O. LVDS provides a low power and low noise environment for reliably transferring data over a serial transmission path. By optimizing the serializer output edge rate for the operating frequency range EMI is further reduced.

DS99R101/DS99R102 Internal DC balanced encoding/decoding is used to support AC-Coupled interconnects.
