Overview
The DS90UB953-Q1 serializer, produced by Texas Instruments, is a key component of the FPD-Link III device family. It is designed to support high-speed raw data sensors, including 2.3MP imagers at 60fps, 4MP cameras at 30fps, satellite RADAR, LIDAR, and Time-of-Flight (ToF) sensors. This serializer delivers a 4.16Gbps forward channel and an ultra-low latency, 50Mbps bidirectional control channel. It supports power over a single coax (PoC) or shielded-twisted-pair (STP) cable, making it ideal for advanced driver-assistance systems (ADAS) and autonomous driving applications. The device is fully AEC-Q100 qualified and operates within a wide temperature range of -40°C to 105°C, packaged in a compact 5mm × 5mm VQFN package.
