Versatile sensor hub can connect serialised data from four video data streams

The Texas Instruments DS90UB960-Q1 is a versatile sensor hub capable of connecting serialised sensor data received from four independent video data streams through an FPD-Link III interface. When paired with a DS90UB953-Q1 serializer, the device receives data from sensors such as imagers supporting full HD 1080p/2MP resolution at 60Hz frame rates. Data is received and aggregated into a MIPI CSI-2 compliant output for interconnecting to a downstream processor. A second MIPI CSI-2 output port is available to provide additional bandwidth or offers a second replicated output for data-logging and parallel processing. The device includes four FPD-Link III deserialisers, each allowing a connection through cost-effective 50Ohm single-ended coaxial or 100Ohm differential STP cables. The receive equalisers automatically adapt to compensate for cable loss characteristics, including degradation over time. Each of the FPD-Link III interfaces also includes a separate low latency bidirectional control channel that continuously conveys I2C, GPIOs, and other control information. General-purpose I/O signals such as those needed for camera synchronisation and diagnostics features also make use of this bi-directional control channel. The device is AEC-Q100 qualified for automotive applications and is provided in a cost-effective and space-saving 64-pin VQFN package.
