ML6430CH中文资料Genlocking Sync Generator with Digital Audio Clock for NTSC, PAL & VGA数据手册Micro Linear规格书

描述 Description

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
■Line locked scalable horizontal pixel clock for an arbitrary number of pixels per line
■Standard frequencies of 12.27, 13.5, 14.75MHz, or 4Fsc
■4´/2´or 2´/1´clock outputs (54 and 27MHz, or 27 and 13.5MHz) and VGA clocks
■Audio clocks: 32, 44.1, or 48kHz, locked to video
■On-chip sync separator, VCO and pulse generator
■Low clock jitter: Short Term: <200ps rms locked
■Line to line: <600ps rms (2.2ns peak-to-peak) locked
■Fast recovery from VCR head switch, stable for fast shuttle speeds and pause
■Single crystal or external frequency source
■PAL, NTSC or VGA operation
■2 wire serial control bus, or selectable presets for stand alone operation
■RS170A compatible
