Abstract :
A high-quality frame-synchronizer for video signal switching and freezing is proposed. In order to realize high-quality frame-synchronization, a novel high-speed and high-definition 11 bit analog-to-digital (A/D) converter which achieves the quite high unweighted S/N ratio performance of 63 dB is developed. It provides synchronized video signal switching by field freezing for high-quality video signal transmission.<>
