Abstract
A communication system for interfacing a transmitting circuit with a receiving circuit includes a transmission interface for receiving data from the transmitting circuit and transmitting the data received over at least one data line in response to a transmission clock signal. The communication system also includes a reception interface configured for receiving the data in response to a reception clock signal and transmitting the data received to the receiving circuit. In particular, the system is configured for generating a plurality of clock signals that have the same frequency but are phase-shifted with respect to one another. In addition, during a calibration phase, the system is configured for selecting one of the clock signals for the transmission clock signal or reception clock signal via selecting at least one of the clock signals for transmission of test signals via the transmission interface and verifying whether the test signals received via the reception interface are correct. The system is further configured to use, during normal operation, the clock signal selected during the calibration phase for transmission of data.
