摘要： A transceiver includes a transceiver and a clock generation unit. The clock generation unit includes a clock generator, a multiplexer, and a frequency difference detector. The transceiver exchanges data with a link partner according to a first clock generated by a phase-locked loop. The clock generator is used for generating and outputting a second clock. The multiplexer is used for receiving a calibration clock or a receiver clock of the link partner, and outputting the calibration clock or the receiver clock of the link partner. The frequency difference detector is used for generating a difference signal according to a difference between the calibration clock and the second clock, or a difference between the receiver clock of the link partner and the second clock. The clock generator adjusts the shift of the second clock according to the difference signal. The phase-locked loop generates the first clock according to the second clock.

摘要： A data transmitting and receiving device and method are used for saving powers and maintaining the connection quality, stability and continuous link. The method includes the step of gradually adjusting the de-emphasis of the signal transmitted from the data transmitting and receiving device according to the setting value thereof. The method also includes the steps of transmitting training sequence signal with an amplitude and the default de-emphasis by the data transmitting and receiving device to the remote device, receiving the training sequence signal from the remote device, thereby the channel attenuation is estimated using the method, and a better de-emphasis is set up. Then, the data transmitting and receiving device gradually increases the amplitude of the training sequence signal and re-transmits it until the remote device receives the training sequence signal transmitted therefrom.
