Overview
The DS90UR910-Q1, produced by Texas Instruments, is an automotive-grade interface bridge chip designed to recover data from the FPD-Link II serial bit stream and convert it into a Camera Serial Interface (CSI-2) format. This chip is compatible with Mobile Industry Processor Interface (MIPI) specifications and supports pixel clocks up to 75 MHz. It is particularly useful in automotive applications, such as central information displays, rear seat entertainment systems, and digital instrument clusters. The device operates on a single 1.8-V power supply and features 1.8-V or 3.3-V compatible LVCMOS I/O interfaces, making it versatile for various system designs.
