NTE7150

Integrated Circuit

Video, Chroma, and Sync. Signal Processing Circuit

for PAL/NTSC/SECAM System Color Televisions

Description:

The NTE7150 is an integrated circuit in a 64–Lead SIP type package designed for PAL/NTSC/SECAM

system color televisions involving video, chroma, and sync. signal processing circuits.

The video section contains a high–performance picture quality emphasis circuit, the chroma section

contains a PAL/NTSC/SECAM system automatic identification circuit, and the sync. section contains

a 50/60Hz automatic identification circuit. The PAL/SECAM demodulating circuit uses a baseband

signal processing system, providing an adjustment–free demodulating circuit. User control functions,
