Overview
The DS90UR910-Q1, produced by Texas Instruments, is an interface bridge chip designed to convert data from the FPD-Link II serial bit stream to the Camera Serial Interface (CSI-2) format. This conversion is compatible with the Mobile Industry Processor Interface (MIPI) specifications. The device is particularly suited for automotive applications, supporting pixel clocks up to 75 MHz and data rates of up to 900 Mbps per data lane over two lanes. It is available in a 40-pin WQFN package and is qualified for the automotive AEC-Q100 grade 2 temperature range of –40°C to 105°C.
