IDENTIFYING CLOCK PHASE GENERATING SYSTEM

摘要

PURPOSE:To detect an optimum switching position between a fixed identification clock and an adaptive identification clock. CONSTITUTION:A generating signal of an adaptive identification clock generating circuit is selected and outputted by using a fixed identification clock generating circuit 2 generating a fixed identification clock after a 1st time t1 from a trailing edge of a frame bit F, an adaptive identification clock generating circuit 4 generating an adaptive identification clock generated after a 2nd time t2 by taking a signal delay between a master station TN and a slave station TE into account, and a clock selection circuit 5 when the 2nd time t2 is delayed more than the 1st time t1.
