SOURCE SERIES TERMINATED DRIVER CIRCUIT WITH PROGRAMMABLE OUTPUT RESISTANCE, AMPLITUDE REDUCTION, AND EQUALIZATION

A source-series terminated ('SST') driver circuit that includes: one or more data signal inputs; one or more control signal inputs; a driver output; and a plurality of driver cells, the driver cells coupled in parallel to one another, outputs of the driver cells coupled together to form th...

Zusammenfassung:A source-series terminated ('SST') driver circuit that includes: one or more data signal inputs; one or more control signal inputs; a driver output; and a plurality of driver cells, the driver cells coupled in parallel to one another, outputs of the driver cells coupled together to form the driver output of the SST driver circuit, where output resistance of the SST driver circuit varies in dependence upon activation of one or more of the parallel driver cells, activation of each driver cell controlled by control signals received at the control signal inputs.
