Abstract

In case microcontroller and digital signal processing blocks are used together in one chip, there has been a problem in which the synchronization of the clocks are not consistent with each other when sending a signal from one block to another. In addition, when a reference clock is activated during a change of input signal, an incomplete interval has occurred. Accordingly, in order to solve the above mentioned problem, the present invention discloses a synchronizing circuit which uses a latch circuit("RS") consisted of NAND gates to synchronize an asynchronous input data and a reference clock, thereby solving the problem in which an incomplete interval occurs.
