<p><P>PROBLEM TO BE SOLVED: To provide a communication mediation device reduced in power consumption during idling. <P>SOLUTION: An internal clock generation circuit 15 starts generation of clock CLK 1 with frequency of 480 MHz in response to detection of arrival of a second packet at a time interval shorter than 125μs that is a first interval by a HS idle detection circuit 10, supplies the clock to a HSDLL (high speed delay line phase locked loop) 16, an elasticity buffer 17, an Rx data deserializer 18, and a Tx data serializer 12, and stops generation of the clock CLK 1 with frequency of 480 MHz in response to detection that the time interval of arrival of the first packet is returned to 125μs. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
