The contributions of supply current values for all four channels are combined at identical data rates.
The V
current 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
The power demands of the quiescent operation of the data channels was 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.
This current is available for driving external loads at the V
capacitive load representing the maximum dynamic load conditions. Refer to the
maximum data rate.
