Serial interface and method for transferring digital data over a serial interface

摘要

A digital serial interface connects a transmitting device with a receiving device for communicating both data bits and synchronization signals via the serial interface. The transmitting device include a primary transmitter for converting a serial sequence of the data bits into successive data signal levels, and further includes a secondary transmitter for converting synchronization signals into synchronization signal levels different from the levels employed for the data signals. The receiving device has a primary receiver for the data signal levels for converting a sequence of data signal levels into a serial sequence of data bits, and further includes a secondary receiver fir the synchronization signal levels for converting synchronization signal levels into synchronization signals.
