Overview
The DS90UB954-Q1 is a dual deserializer hub developed by Texas Instruments, designed to receive serialized sensor data from one or two independent sources through an FPD-Link III interface. This component is particularly suited for automotive and industrial applications, given its AEC-Q100 qualification and robust operating temperature range of –40°C to +105°C. When paired with compatible serializers like the DS90UB953-Q1, it supports high-resolution cameras and various sensors such as RADAR, ToF, and LIDAR, aggregating data into MIPI CSI-2 compliant outputs for downstream processing.
