TEXAS INSTRUMENTS DS90UR124QVS 总线, CAN, 3 V, 3.6 V, TQFP
The is a 24-bit DC-balanced FPD-Link II Serializer and Deserializer 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 colour depth: RGB666 + HS, VS, DE + three 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. The device saves system cost by narrowing data paths that in turn reduce PCB layers, cable width and connector size and pins. The DS90URxxx-Q1 incorporates FPD-Link II LVDS signalling 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.
