Abstract

PURPOSE: To make it possible to apply a continuous synchronization system of excel lent transmission efficiency and also to eliminate the need for another timing line by detecting the polarity change of received data and then by sampling the received data by the value of a counter at this time.
CONSTITUTION: When the polarity of received data input 1 changes, output 29 becomes "1" at the fall of clock 2 and "0", "0" and "1" are stored in FFs 30, 31 and 32 respectively; and when the value of counter 3 reaches 30, output 40 becomes "1", all FFs are cleared and received-data sampling clock output 42 becomes "0". As a result, output 42 becomes pulses whose single period is 30 times as long as clock input 2. At this time, FFs 30, 31 and 32 are all cleared to make output 40 "0" and the operation starts from the initial state.
