Modified fiber-optic serial communication for cascaded multilevel converters

This paper proposed a novel automatic synchronization and multiple serial transfer clock frequency method (AS&MSC) for the fiber optic communication that is appropriate to cascade converters with better bit error rate performance. Comparing with conventional method, this method could automatically synchronize the transmitter and receiver without clock signals. Furthermore, the receiver could obtain the serial data with high resolution because of the multiple transfer clock. This paper also illustrated the FPGA implementation of this method, and the experimental results display that the proposed method has excellent performance to eliminate the transmission errors.
