ABSTRACT:
A network device includes an input, at least one port, a frequency doubler, a data I/O device, and a variable delay circuit. The input is for receiving an external clock signal. The frequency doubler is coupled to the input and configured to receive an input signal and output an output signal with a frequency double that of the input signal. The data I/O device is configured to output data to the at least one port based on a reference clock signal. The variable delay circuit is located between the data I/O device and at least one port. An external clock signal received at the input is input into the frequency doubler. The output signal of the frequency doubler is applied to the data I/O device as the reference clock signal, and the output data is delayed by the variable delay circuit.
