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.
