3.4.1 Power over Coax (PoC)

The DS90UB960 device supports PoC to power remote sensor systems. The power is delivered through the same Coax cable that transmits video data from the sensors. PoC is achieved through a network of filters that isolate the transmission line from the loading of the DC-DC regulator circuits and their connecting power traces on both sides.

J22 is named Camera and controls Bank2 voltages for the sensors. J27 is named Radar and controls the Bank1 voltages. On the Fusion board, there are two voltage options to choose from: 5 V and 12 V. Two separate jumpers select the voltage of choice: J27 and J22. There is also a switch (S3 position 3) for Bank1 to choose if Coax or HSD sensors are used. Regardless, the voltage selected is used for the HSD or Coax, and the method must be selected by the switch as just mentioned.
