Description

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