Abstract
An IC uses a tunable interconnect driver between a data source and a data destination to selectively slow down ('de-tune') data signals. Data sent along relatively short paths are de-tuned to reduce power supply noise during synchronous switching events. In some embodiments, the tunable interconnect driver delays data transmission relative to an un-delayed signal path, in other embodiments, the slew rate of the tunable interconnect driver is selectively reduced.
