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.
