AN2492FH
Luminance and chrominance signal processing circuit for
8 mm video (NTSC)
s Overview
The AN2492FH is a single chip LSI on which Y/C
main signal processing circuit of NTSC normal 8 mm
VCR is integrated. It is possible to reduce the system
cost drastically thanks to the introduction of an external
filter on to the chip and fc auto adjustment.
s Features
• 5 V single power supply
• Reduction of the external components and adjusting
parts by adopting automatic adjustment filter
• No need of glass delay lines
• For NTSC (PAL: AN2493 pin-compatible)
