M52693SP
BURST LOCK CLOCK GENERATOR
DESCRIPTION
The M52693SP is a semiconductor integrated circuit developed for
analog signal processing of a picture-in-picture system, consisting
of a sync separator, an ACC, a burst lock clock generator circuit,
an analog switch and a clamp circuit, etc. It is also available on
digital video signal systems other than the above.

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
