Description:

The NTE879 is an integrated circuit in a 20–Lead DIP type package used to generate a composite TV signal from baseband red, blue, green, and sync inputs. This device has color subcarrier oscillator, voltage controlled 90° phase shifter, two DSB suppressed carrier chroma modulators, RGB input matrices, and blanking level clamps. It can be operated with very few external parts, but has the pin–outs for a fully implemented, top quality composite signal. It is ideal for encoding signals from color cameras and graphic generators.

Features:

● Reference Oscillator Self–Contained or Externally Driven

● Nominal 90° ±5° Axes are Optionally Trimmable

● Simple PAL/NTSC Switch

● Luminance and Chroma Channels can accept Delay Line/Bandpass Elements or Direct Connection

● Provides DC Reference to Permit Direct Drive to RF Modulator
