Integrated Circuit
Color TV Video Signal/Chrominance
Signal Processing Circuit
Description:
The NTE7112 is an integrated circuit in an 18–Lead DIP type package designed for use in color TV
video signal and chrominance signal processing circuits.
Features:
Chrominance signal processing circuitry for either PAL or SECAM system color TV receivers
can be made by using the NTE7112 in combination with the AN5622 and the AN5630N:
PAL System: NTE7112, AN5622
SECAM System: NTE7112, AN5622, AN5630N
Incorporating luminance signal mixer circuit, provides R, G, B original color output
DC Transmission Quality: 100%
All DC controlled adjustment simplifies wiring operation (Color/Contrast/Brightness adjustment)
