The DS90UB954TRGZRQ1 is available from a power supply of 1.71V to 1.89V and is available in an a4-pin VQFN package for easy shipping. The operating temperature range of the device is -40°C ~ 105°C.

The DS90UB954TRGZRQ1 is a versatile dual deserializer hub that receives serial sensor data from one or two independent sources via the FPD-Link III interface.

The DS90UB954TRGZRQ1 receives and aggregates data from one or two sensors. When the CSI-2 interface is configured for 2-channel operation, a duplicate MIPI CSI-2 clock channel is provided to provide a replication output. Copy mode creates two copies of an aggregated video stream.

The DS90UB954TRGZRQ1 chipset is AEC-Q100 compliant and is used to receive data over a 50Ω single-ended coaxial cable or a 100Ω differential STP cable. The deserializer hub is ideal for coaxial cable-powered applications, and the receive equalizer automatically adapts to compensate for cable loss characteristics (no additional programming required), including degradation over time.

Each FPD-Link III interface includes a separate low-latency bidirectional control channel (BCC) that continuously transmits I2C, GPIO, and other control information. GPIO signals for sensor synchronization and diagnostic functions also use BCC.
