2.5.3 Sensor Interface / Twisted Pair

The add-on board can support a total of four twisted pair (TP) inputs for interfacing with image sensors. The four TP interfaces are not supported by default. The Port 0 deserializer (UB9702-Q1) supports Coax by default, but can be updated to support TP my moving of in-line capacitors (requires soldering). See schematic for details on which components are to be moved to switch from Coax to TP.

Similar to the coax interfaces, each TP interface supports sensors paired with either DS90UB953 or DS90UB971 serializers. The design uses Rosenberger HSD connectors for TP. The HSD connector supports four separate wires and connections, two used for the TP data, one for power, and one for ground and return.
