A system and method for reducing simultaneous switching output (SSO) noise. In one embodiment, power supply decoupling capacitances are distributed non-uniformly among a plurality of I/O circuits. Transitions between consecutive values on a data bus are either sent by the transmitter as requested at the input of the transmitter, or, in cases for which the noise of the requested transition is high, converted by an encoder to transitions having lower SSO noise. The converted transitions are decoded in a receiver, so that the data at the output of the receiver are the same as the data at the input to the transmitter. |
