Camera hub capable of connecting serialised data received from four video datastreams

The Texas Instruments DS90UB964-Q1 is a versatile camera hub capable of connecting serialised camera data received from four independent video datastreams via an FPD-Link III interface. When coupled with DS90UB913AQ/913Q/933Q serialisers, the device receives data from 1-megapixel image sensors supporting 720p/800p/960p resolution at 30Hz or 60Hz frame rates. Data is received and aggregated into a MIPI CSI2 compliant output for interconnect to a downstream processor. A second MIPI CSI2 output port is available to provide additional bandwidth, or offers a second replicated output. The device includes four FPD-Link III deserialisers, each enabling a connection via cost-effective 50ohm single-ended coaxial or 100ohm differential STP cables. The receive equaliser automatically adapts to compensate for cable loss characteristics, including degradation over time. Each of the interfaces also includes a separate low latency bi-directional control channel that conveys control information from an I2C port and is independent of video blanking period. General purpose I/O signals such as those required for camera synchronisation and functional safety features also make use of this bi-directional control channel.
