The DS90UB960-Q1 is a versatile sensor hubcapable of connecting serialized sensor data receivedfrom four independent video data streams through anFPD-Link III interface. When paired with aDS90UB953-Q1 serializer, the DS90UB960-Q1receives data from sensors such as imagerssupporting full HD 1080p/2MP resolution at 60-Hzframe rates. Data is received and aggregated into aMIPI CSI-2 compliant output for interconnect to a　downstream processor. A second MIPI CSI-2 outputport is available to provide additional bandwidth, oroffers a second replicated output for data-logging andparallel processing.

The DS90UB960-Q1 includes four FPD-Link IIIdeserializers, each enabling a connection throughcost-effective 50-Ω single-ended coaxial or 100-Ωdifferential STP cables. The receive equalizersautomatically adapt to compensate for cable losscharacteristics, including degradation over time.

Each of the FPD-Link III interfaces also includes aseparate low latency bidirectional control channel thatcontinuously conveys I2C, GPIOs, and other controlinformation. General-purpose I/O signals such asthose required for camera synchronization and　diagnostics features also make use of thisbidirectional control channel.The DS90UB960-Q1 is AEC-Q100 qualified forautomotive applications and is offered in a costeffectiveand space-saving 64-pin VQFN package.
