Overview
The DS90UR241QVSX/NOPB is a 5-43MHz DC-Balanced 24-Bit FPD-Link II Serializer produced by Texas Instruments. This automotive-grade component is designed to translate a 24-bit parallel bus into a fully transparent data/control FPD-Link II LVDS serial stream with embedded clock information. It is particularly suited for driving graphical data to displays requiring 18-bit color depth, such as RGB666 + HS, VS, DE, and three additional general-purpose data channels. The device simplifies the transfer of a 24-bit bus over PCB traces and cable, eliminating skew problems between parallel data and clock paths, and reduces system costs by minimizing data paths, PCB layers, cable width, and connector size and pins.
