Abstract
The present invention discloses a transceiver apparatus having phase-tracking mechanism. A phase detection circuit of a receiver circuit performs sampling and phase detection on an input data signal according to a sampling clock signal to generate a phase detection result. A proportional gain circuit of the receiver circuit applies a proportional gain operation on the phase detection result to generate a phase adjusting signal. A CDR circuit of the receiver circuit receives a source clock signal to generate the sampling clock signal and performs phase-adjusting according to the phase adjusting signal. The integral gain circuit apples an integral gain operation on the phase detection result to generate a frequency adjusting signal. The source clock generating circuit receives a reference clock signal to generate the source clock signal and perform frequency-adjusting according to the frequency adjusting signal. The transmitter circuit performs signal transmission according to the source clock signal.
