3 Description
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 bi-
directional control channel.
