NTE879

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 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: 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 Connection D Provides DC Reference to Permit Direct Drive to RF Modulator Absolute Maximum Ratings: Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V 8.2Vdc Regulator Output Current, IREG . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10mA Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.25W Derate Above 25°C . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10mW/°C ...
