DS90UR241/DS90UR124 5-43 MHz DC-Balanced 24-Bit LVDS Serializer and
Deserializer
General Description
The DS90UR241/124 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 DS90UR241/124 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...
