AN5195K-C
Single chip IC for PAL/NTSC color TV
(built-in I
2
C bus interface)
s
Overview
The AN5195K-C is an IC in which all of the
PAL/NTSC system color television signal process-
ing circuits are integrated on one chip. The ratio-
nalization of set production line can be realized by
the incorporation of I
2
C bus interface.
s
Features
Built-in video IF circuit, sound IF circuit, video
signal processing circuit, color signal processing
circuit, and sync. signal processing circuit
Rationalization of set production line can be real-
ized by the incorporation of I
2
C bus interface
Can be applied to PAL/NTSC/AV-NTSC/M-
NTSC system
Package: 64-SDIP, supply voltage: 5 V, 9 V
