20090190631 | METHOD FOR GENERATING A SPREAD SPECTRUM CLOCK AND APPARATUS THEREOF - A method for generating a spread spectrum clock includes the steps of providing a reference clock having a reference period; generating a plurality of output clocks respectively having different phases according to the reference clock; generating a first/second control signal according to the reference clock and a spread spectrum clock and starting a first/second duration accordingly; during the first/second duration, outputting a first/second selecting signal representing a first/second predetermined sequence according to the first/second control signal, wherein the second predetermined sequence is a substantial reversed sequence of the first predetermined sequence; and during the first/second duration, sequentially outputting some or all of the output clocks as the spread spectrum clock according to the first/second predetermined sequence. | 07-30-2009 |
20090193109 | POWER-SAVING NETWORK APPARATUS AND METHOD THEREOF - A power-saving network apparatus includes a MAC and a PHY. The PHY includes a transmitter and a receiver. The transmitter executes the operations of: transmitting a data signal to a remote network apparatus according to output packets of the MAC when the transmitter enters a normal state; transmitting an idle signal to the remote network apparatus when the transmitter enters an idle state; transmitting an indication signal to the remote network apparatus to notify it to enter a low power state, wherein the indication signal is different from the idle signal; entering the idle state or the normal state from the low power state in response to at least one of a predetermined period and a transmitting enable signal. | 07-30-2009 |
20100169704 | Ethernet System and Related Clock Synchronization Method - 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. | 07-01-2010 |
20150103676 | METHOD FOR DETERMINING CONNECTION STATUS OF WIRED NETWORK - 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. | 04-16-2015 |
