The contributions of supply current values for all four channels are combined at identical data rates.

proportional to the data rate. Additional supply current associated with an individual channel operating at a given data rate can be calculated as described in the

3

The power demands of the quiescent operation of the data channels is not separated from the power supply section. Efficiency includes the quiescent power

consumed by the I/O channels as part of the internal power consumption.

representing the maximum dynamic load conditions. Refer to the Power Consumption section for calculation of the available current at less than the maximum data rate.
