Title:
CLOCK TRANSFER CIRCUIT, VIDEO PROCESSING SYSTEM, AND SEMICONDUCTOR INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2013/179349
Kind Code:
A1
Abstract:
A clock transfer circuit receives input data synchronized with a first clock and outputs the received input data as output data synchronized with a second clock having a different frequency. A write address control unit (23) operates in synchronization with the first clock and supplies a write address to a memory (21). A read address control circuit (24) operates in synchronization with the second clock and supplies a read address to the memory (21). A frequency comparator (30) compares the input data with the output data in the frequency of a predetermined event. Based on this comparison result, clock adjustment units (14, 15) adjust the frequency of the second clock.
