Overview
The DS90UB953TRHBRQ1 is a high-speed serializer part of Texas Instruments' FPD-Link III device family. This component is designed to support high-speed raw data sensors, including cameras, RADAR, LIDAR, and Time-of-Flight (ToF) sensors. It is particularly suited for applications requiring low latency and high data throughput, such as advanced driver assistance systems (ADAS) and industrial imaging. The serializer operates with a single 1.8V power supply and features ultra-low power consumption, making it ideal for space-constrained and power-sensitive designs.
