ICs for VCR
AN2493FH
Luminance and chrominance signal processing (PAL) IC
for 8 mm VCR
Unit: mm
s
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 built-
in of external filters and fc automatic adjustment.
