摘要:
Techniques for controlling a driver to reduce data dependent noise, such as simultaneous switching effects and cross-talk effects. A plurality of drivers may each receive a data segment to transmit and a plurality of data segments that other drivers will transmit. A driver controller may adjust the time at which the data segment is transmitted in response to the plurality of data segments that the other drivers will transmit. The adjustment may compensate for simultaneous switching noise and cross-talk by, for example, delaying the transmission of a data segment or changing the slew rate of the signal carrying the data segment.
