explain
DS90UB954-Q1 is a multi-functional dual channel deserializer hub, which can receive serial sensor data from one or two independent sources through FPD-Link III interface. When used with DS90UB953-Q1 serializer, DS90UB954-Q1 receives data from imager, supports 2MP/60fps and 4MP/30fps cameras, satellite radar and other sensors (such as ToF and laser radar). The received data will be aggregated to the output that complies with MIPI CSI-2 standard and is interconnected with the downstream processor.
For sensors equipped with DS90UB933-Q1 and DS90UB913A-Q1 serializers, DS90UB954-Q1 operates from one or two sensors
(Including full HD 1080p 2MP 60/fps imager sensor) Receive and aggregate data. When configuring CSI-2 interface for 2-channel operation
Provide an identical MIPI CSI-2 clock channel to provide duplicate output. Replication mode creates two aggregated video stream copies for data
Recording and parallel processing.
The DS90UB954-Q1 and the accompanying DS90UB953-Q1 chipset meet AEC-Q100 standards and are designed to be used via a 50 Ω single ended coaxial cable or
100 Ω differential STP cable receives data. The deserializer hub is ideal for coaxial cable powered applications, and the receive equalizer automatically adapts to compensate
Cable loss characteristics (without additional programming), including cable aging over time.
Each FPD-Link III interface includes a separate low delay bidirectional control channel (BCC), which can continuously transmit I2C, GPIO and other control information. The GPIO signals used for sensor synchronization and diagnostic features also use BCCs.
