Overview
The DS90UR124QVSX/NOPB is a 5MHz to 43MHz DC-Balanced 24-Bit FPD-Link II Deserializer produced by Texas Instruments. This automotive-grade component is AEC-Q100 grade 2 qualified, ensuring its reliability and performance in harsh automotive environments. The chipset is part of the DS90URxxx-Q1 family, designed to translate a 24-bit parallel bus into a fully transparent data/control FPD-Link II LVDS serial stream with embedded clock information. This design simplifies the transfer of graphical data to displays requiring 18-bit color depth, such as RGB666 + HS, VS, DE, and three additional general-purpose data channels.
