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,
system switching, etc. are controlled via the I²C bus.
