Texas Instruments DS90UB638-Q1 4.16Gbps Single Input Deserializer

Texas Instruments DS90UB638-Q1 4.16Gbps Single Input Deserializer 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 satellite RADAR, 2MP/60fps and 4MP/30fps cameras, and other sensors such as LIDAR and ToF. Data is received and presented at a MIPI CSI-2 compliant output for interconnecting 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 parallel processing and data logging.

The Texas Instruments DS90UB638-Q1 is AEC-Q100 qualified and designed to receive data across a 50Ω, single-ended coaxial. The deserializer is ideal for Power-over-Coax (PoC) applications. 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). The BCC continuously conveys I²C, GPIO, and other control information. GPIO signals purposed for sensor synchronization and diagnostic features also use the BCC.
