This chipset is ide- ally suited for driving graphical data to displays requiring 18- bit color depth - RGB666 + HS, VS, DE + 3 additional general purpose data channels. This single serial stream simplifies transferring a 24-bit bus over PCB traces and cable by elim- inating 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 FPD-Link II LVDS signal- ing on the high-speed I/O. FPD-Link II 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 fur- ther reduced. In addition, the device features pre-emphasis to boost signals over longer distances using lossy cables. Internal DC bal- anced encoding/decoding is used to support AC-Coupled interconnects. Using National Semiconductor’s proprietary random lock, the Serializer’s parallel data are randomized to the Deserializer without the need of REFCLK.
