Overview
The DS90UR910-Q1, produced by Texas Instruments, is an 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 conversion is compatible with Mobile Industry Processor Interface (MIPI) specifications. The device supports pixel clocks up to 75 MHz and is capable of recovering data up to 10 meters over STP cable. It is particularly suited for automotive applications due to its AEC-Q100 Grade 2 qualification and operating temperature range of –40°C to 105°C.
