TI DS90UB954TRGZRQ1

DS90UB954-Q1 is a versatile dual deserializer hub that receives serial sensor data from one or two independent sources via FPD-Link III interfaces. When used with the DS90UB953-Q1 serializer, the DS90UB954-Q1 receives data from imagers, supporting 2MP/60fps and 4MP/30fps cameras as well as satellite radar and other sensors such as ToF and LiDAR. The received data is aggregated to an output compliant with MIPI CSI-2 for interconnection with downstream processors. For sensors equipped with DS90UB933-Q1 and DS90UB913A-Q1 serializers, the DS90UB954-Q1 receives and aggregates data from one or two sensors, including full HD 1080p 2MP 60fps imager sensors. When the CSI-2 interface is configured for 2-channel operation, an identical MIPI CSI-2 clock channel is provided to deliver a replicated output. Replication mode creates two copies of the aggregated video stream for data logging and parallel processing. The DS90UB954-Q1 and its companion DS90UB953-Q1 chipset are AEC-Q100 qualified and designed to receive data over 50Ω single-ended coaxial cable or 100Ω differential STP cable. The deserializer hub is well suited for coaxial cable power applications, with a receive equalizer that automatically adapts to compensate for cable loss characteristics — requiring no additional programming — including cable aging over time. Each FPD-Link III interface includes a dedicated low-latency bidirectional control channel (BCC) that continuously carries I2C, GPIO, and other control information. GPIO signals for sensor synchronization and diagnostic functions are also conveyed over the BCC.
