摘要： A master device for an Ethernet system is disclosed. The master device includes a receiver, a buffer, a phase lock loop unit, and a transmitter. The receiver is used for generating phase adjustment data according to transmission data sent by a slave device when the master device operates during a switch mode. The buffer is coupled to the receiver for accumulating the phase adjustment data and outputting a phase adjustment value. The phase lock loop unit is coupled to the buffer for adjusting the phase of an output clock according to the phase adjustment value to maintain a fixed phase difference between the recovery clock and the output clock. The transmitter is used for transmitting initialization data to the slave device according to the output clock.

摘要： A network processor includes a transceiver circuit, a network data processing unit, and a clock signal control unit. The transceiver circuit transmits and receives a network signal, compares a voltage level of the network signal with a threshold value, outputs a comparison result, and operates under a first clock signal. The network data processing unit is coupled to the transceiver circuit to process the network signal, and operates under a second clock signal different from the first clock signal. The clock signal control unit disables supply of the second clock signal to the network data processing unit when the voltage level is smaller than the threshold value, and enables supply of the second clock signal to the network data processing unit when the voltage level is not smaller than the threshold value. An energy saving method for a network processor is also disclosed.

摘要： A method applied to a wired network including a first network device and a second network device is disclosed. The first and second network devices each include a first set of connection ends and a second set of connection ends. Firstly, the first network device transmits a specific signal pattern through its first set and second set of connection ends. Then, the first network device detects whether a signal is received at its first set and second set of connection ends. If it is determined that a signal is not received at the first set connection ends while a signal is received at the second set connection ends, the first network device determines that its second set of connection ends is not correctly coupled to the second set of connection ends of the second network device.
