Abstract:
Methods, apparatus, and systems for communication over a C-PHY interface are disclosed. A transmitting device has a driver circuit configured to drive a three-wire bus in accordance with a symbol received at an input of the driver circuit, a pattern detector receives a sequence of symbols to be transmitted over the three-wire bus in a plurality of transmission symbol intervals, and a selection circuit responsive to a select signal provided by the pattern detector and configured to select between delayed and undelayed versions of a current symbol to drive the input of the driver circuit during a corresponding transmission symbol interval. The select signal may select the delayed version of the current symbol when a combination of the current symbol with an immediately preceding symbol cause the pattern detector to indicate a pattern match.
