ABSTRACT:
A system and method for a predriver and driver interface having scalable output drive capability with corresponding scalable power is disclosed. The system includes a predriver to driver interface having a data source; a plurality of predrivers, each coupled to the data source and responsive to an enable signal, for driving a predriven data signal only when a corresponding enable signal is asserted and for consuming reduced power when the corresponding enable signal is deasserted; a plurality of drivers, each coupled to one of the plurality of predrivers to receive a corresponding predriven data signal from the corresponding predriver and responsive to the enable signal coupled to the corresponding predriver, for driving an output with the predriven data signal only when the corresponding enable signal is asserted and for consuming reduced power when the corresponding enable signal is deasserted; and a controller, coupled to the predrivers and the drivers, for selectively asserting the enable signals to provide variable output drive capability of the data source to the output while providing scalable power consumption.
