The DS90UB954-Q1 is a versatile deserializer capable of receiving serialized camera data from 1 or 2 independent video datastreams via an FPD-Link III interface. When paired with a DS90UB953-Q1 serializer, the DS90UB954-Q1 receives data from imagers supporting 2MP/60fps and 4MP/30fps cameras as well as satellite RADAR. Data is received and aggregated into a MIPI CSI-2 compliant output for interconnect to a downstream processor. For cameras with DS90UB933-Q1/DS90UB913A-Q1 serializers, the DS90UB954-Q1 receives and aggregates data from imagers supporting 1MP/60fps and 2MP/30fps as well. When configuring the CSI-2 interface for 2-Lane operation a second MIPI CSI-2 output port is available to provide a second replicated output. Replication mode creates 2 copies of the aggregated video stream for datalogging and parallel processing.
●The DS90UB953/954-Q1 chipset is fully AEC-Q100 qualified and designed to receive data across either 50-Ω single-ended coaxial or 100-Ω differential STP cables. The receive equalizer automatically adapts to compensate for cable loss characteristics, including degradation over time with no additional programming required.
●Each of the FPD-Link III interfaces also includes a separate low latency bi-directional control channel that continuously conveys I2C, GPIO, and other control information. General purpose I/O signals such as those required for camera synchronization and diagnostic features also make use of this bidirectional control channel.
