2.5.2 Sensor Interface / Coax

The add-on board supports a total of 12 coax inputs for interfacing with image sensors. Each coax interface supports sensors paired with either DS90UB953 or DS90UB971 serializers. The design uses Rosenberger FAKRA connectors for connecting with coax cables.

Power-over-coax is provided on each interface to power the image sensor or serializer. The voltage provided to each is 12 volts and is current limited to 2A.

Note: Design is limited to about 10Amps on the 12V regulator, thus cannot support maximum power simultaneously to all 12 interfaces.

Connectors [J4] [J7] [J10] [J13] are connected to one UB9702-Q1 and are aggregated on CSI Port 0. Connectors [J15] [J16] [J17] [J18] are connected a second UB9702-Q1 and are aggregated to CSI Port 1. Connectors [J14] [J11] [J8] [J4] are connected to a third UB9702-Q1 and are aggregated to CSI Port 2.

Depending on the capability of the base EVM, the number of supported CSI ports and camera inputs can vary.
