Patent ID: 8861573

Claim:
A transceiver for adjusting a transmitting clock, the transceiver comprising: a transmission unit, for transmitting a transmission signal according to the transmitter clock; a reception unit, for receiving a reception signal, and generating a receiving clock according to the reception signal; and a transmitting clock tracking unit, coupled to the transmission unit and the reception unit, wherein the transmitting clock tracking unit comprises a configuration unit, the configuration unit stores a clock threshold bound, and the transmitting clock tracking unit controls a frequency of the transmitting clock of the transmission unit according to the receiving clock and the clock threshold bound; wherein the frequency of the transmitting clock is within the clock threshold bound, and the clock threshold bound comprises a first clock threshold and a second clock threshold, and the first clock threshold is greater than the second clock threshold; the transceiver adjusts the frequency of the transmitting clock to the first clock threshold when a frequency of the receiving clock is higher than first clock threshold; the transceiver adjusts the frequency of the transmitting clock to the second clock threshold when the frequency of the receiving clock is lower than the second clock threshold; and the transceiver tracks the frequency of the receiving clock to adjust the frequency of the transmitting clock when the frequency of the receiving clock is in within the clock threshold bound.
