摘要: A multi-rate transponder system has a receiving part, a system controller and a transmitting part. The receiving part includes a data transfer circuit, a clock transfer circuit, and a reference clock circuit. The receiving part receives the incoming serial data stream and derives a clock signal and a data signal. The data transfer circuit generates an incoming data signal based on the derived data signal. The clock transfer circuit generates a receiver clock signal. The reference clock circuit generates a reference clock signal for the transmitting part based on the derived clock signal. The system controller includes system data receiving and transferring means, and system data processing means. The system data receiving means receives the incoming data signal and the receiver clock signal and provides the incoming data signal for clock domain transfer. The system data processing means processes the incoming data signal to generate an outgoing data signal to the system data transfer means. The system data transfer means provides the outgoing data signal to the transmitting part in response to a transmitter clock signal. The transmitting part generates an output clock signal based on the reference clock signal, and includes a transmitter clock circuit to generate the transmitter clock signal to the system data transfer means, a data reception circuit to receive the outgoing data signal from the system data transfer means and to generate the serial outgoing data stream at an appropriate bit rate depending on the outgoing data signal and the output clock signal.
