Each PoC network has a maximum current rating based on the saturation characteristics of the components. As discussed in Section 2.1, inductors saturate, dissipate heat, and pass very high frequencies when the maximum current rating is not respected. The individual operating specifications of every PoC component must be followed to provide proper filtering.

The PoC network must have a current rating that allows for an appropriate amount of power to be supplied to the serializer and sensor. The maximum power drawn by the serializer board can be calculated from the worst-case scenario power consumption of the serializer side of the link. An example of a potential maximum power consumption scenario is a period where the sensor is actively gathering data and all other remote devices are operating. Please note that the worst-case scenario and maximum power consumption is system dependent and can vary across designs. The IR drop due to the parasitic impedance of the individual components and cables must also be considered. TI recommends several different PoC networks capable of different levels of power delivery. The chosen PoC network must be capable of supplying enough current and power from the given PoC voltage for the serializer and sensor.
