DS90UR241 124 Deserializer and Serializer

5-43 MHz DC-balanced 24-bit FPD-Link II chipset from Texas Instruments

Texas Instruments' DS90UR241/124 Deserializer and SerializerTexas Instruments' DS90UR241/124 chipset translates a 24-bit parallel bus into a fully transparent data/control FPD-Link II LVDS serial stream with embedded clock information. This chipset is ideally 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 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 FPD-Link II LVDS signaling 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 further reduced. In addition, the device features pre-emphasis to boost signals over longer distances using lossy cables. Internal DC balanced 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.
