2.3.2 DS90UB971S-Q1

The DS90UB971S-Q1 is a serializer which is designed to support ultra-high-speed raw data sensors including 8MP+ Imagers, satellite RADAR, LIDAR, and Time-of-Flight (ToF) sensors. The chip delivers an 7.55Gbps forward channel with an ultra-low latency of 47.1875Mbps bidirectional control channel. The device supports power over a single coax or STP cable. The DS90UB971S-Q1 features advanced data protection and diagnostic features used for automotive applications such as ADAS to achieve functional safety. Together with a companion Texas Instrument’s deserializer, the DS90UB971S-Q1 delivers precise multi-camera sensor clock and sensor synchronization. In addition, the device features I2C interface, SPI, and up to 8GPIOs.

The DS90UB971S-Q1 is fully AEC-Q100 qualified with a wide temperature range of –40°C to 115°C. The serializer comes in a small 5mm × 5mm VQFN package for space-constrained sensor applications.
