摘要： A frequency-phase adjusting device includes a first controller, a second controller, and an oscillating circuit. The first controller generates a first control signal according to a target frequency and a current frequency. The second controller generates a second control signal according to the first control signal, wherein the second control signal is related to a first frequency difference, a second frequency difference, and a designated duration. The oscillating circuit adjusts the current frequency according to the first frequency difference, the second frequency difference, and the designated duration. The current frequency is set as a first frequency during a first duration, set as a second frequency during the designated duration, and set as a third frequency during a second duration. The first frequency difference equals a difference between the first frequency and the second frequency, and the second frequency difference equals a difference between the second frequency and the third frequency.

摘要： A communication system includes a first network device and a second network device. A power consumption control method applied to the communication system includes the steps of: checking a receiving capability of the first network device to generate a first checking result; and selectively notifying the second network device to adjust a transmitting capability of the second network device according to the first checking result. When the first checking result indicates that the receiving capability of the first network device is greater than a first threshold, transmit a first notice signal to notify the second network device. When receiving the first notice signal, lower the transmitting capability of the second network device.

The transceiver comprises an auto-negotiation circuit, a timing recovery circuit, an interference cancellation circuit and an equalizer. The auto-negotiation circuit performs an auto-negotiation procedure to determine whether the transceiver operates as a master or slave transceiver.
