Patent ID: 8537905

Claim:
A method for adjusting interconnect power levels comprising: providing a voltage regulating device in communication with a voltage supply port of a driver of a high-speed differential serial link, the voltage regulating device for providing a regulated supply voltage to the driver; receiving at a control port of the voltage regulating device a control signal indicative of a predetermined regulated voltage for provision to the driver for a pre-selected type of data transmission to a receiver via the high-speed differential serial link, the pre-selected type of data transmission having a corresponding interconnect power level; using the voltage regulating device providing the regulated supply voltage to the driver by selecting one of a plurality of predetermined reference voltages corresponding to the pre-selected type of data transmission and providing the selected predetermined reference voltage to the driver; using the driver transmitting a data signal according to the pre-selected type of data transmission to the receiver; providing a switch control signal to the receiver, the switch control signal being indicative of a low-speed data transmission; and, switching the receiver into a reflective wave transmission mode in which only dynamic power is consumed while static power consumption is reduced to zero.
