NTE879
Integrated Circuit
RGB to PAL/NTSC Encoder for Color TV
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 ma-
trices, 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 camer-
as and graphic generators.
Features:
D Reference Oscillator Self–Contained or Externally Driven
D Nominal 90° ±5° Axes are Optionally Trimmable
D Simple PAL/NTSC Switch
D Luminance and Chroma Channels can accept Delay Line/Bandpass Elements or Direct Con-
nection
D Provides DC Reference to Permit Direct Drive to RF Modulator
