AN2493FH
Luminance and chrominance signal processing (PAL) IC for 8 mm VCR
Overview
The AN2493FH is a single chip LSI designed for a Y/ C main signal processing of PAL system normal 8 mm video. System cost can be cut down drastically by built­in of external filters and fc automatic adjustment.
Features
5 V single power supply
Reduction of external components and adjustment parts
by adopting of automatic adjustment filters.
No need of glass delay lines.
