Synchronous CDMA/spread spectrum methods, devices, and systems are used to suppress crosstalk in clock-forwarded on-chip interconnects. Transmitting a spread spectrum signal across on-chip interconnects for recovery at the terminus permit integrated chip designers to overcome the effects of capacitive cross-talk between adjacent data bus lines. The methods, devices, and systems provided herein improve cross-talk immunity between adjacent high speed signal lines by applying synchronous CDMA spread spectrum techniques to some or all of the high speed signal lines. Other methods, devices, and systems provided herein apply synchronous CDMA spread spectrum techniques to the concept of sending phantom signals to reduce the number of signal lines used to carry data.
A data bus for transmitting data on an integrated circuit comprising:
