The DS90UB638-Q1 is a versatile deserializer capable of receiving serialized sensor data from a source through an FPD-Link III interface. When paired with a DS90UB635-Q1 serializer, the DS90UB638-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. Data is received and presented at a MIPI CSI-2 compliant output for interconnect to a downstream processor. When configuring the CSI-2 interface for 2-lane operation, a duplicate MIPI CSI-2 clock lane is available to provide a replicated output. Replication mode creates two copies of the received video stream for data logging and parallel processing.

The DS90UB638-Q1 is AEC-Q100 qualified and designed to receive data across a 50-Ω, single-ended coaxial. The deserializer is ideal for Power-over-Coax applications and the receive equalizer automatically adapts to compensate for cable loss characteristics with no additional programming required, including degradation over time.

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