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.
