32mA (Typ.)
Built-in 4fsc burst lock clock generator circuit required for digital
video signal processing
Small picture chroma level following main picture burst level
Main picture pedestal level matching small picture pedestal level
Built-in reference voltage source for A/D converter
APPLICATION
TV, VCR
RECOMMENDED OPERATING CONDITION
Supply voltage range......................................................4.7 to 5.3V
Rated supply voltage.................................................................5.0V
