ML6430中文资料MICRO-LINEAR数据手册PDF规格书

GENERAL DESCRIPTION

The ML6430/ML6431 are multi-standard single-chip BiCMOS video Genlock ICs for NTSC, PAL and VGA.

They are designed to provide a stable clock from an analog video signal, and to provide timing pulses for clamping, decoding, blanking and processing video signals. The ML6430/ML6431 handle VCR glitches and variations created by head switching, tape dropouts, missing sync pulses, freeze frames, high speed playback and camcorder gyro errors.

FEATURES
