ECG879 RGB to PAL/NTSC Encoder for Color TV ~ 20 Pin DIP (NTE879). The ECG879 is an integrated circuit in a 20 Pin DIP type package used to generate a composite TV signal from base band 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 Replaces: NTGE879 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 Junction Temperature, TJ: +150°C Operating Temperature Range, TA: 0° to +70°C Storage Temperature Range, Tstg: -65° to +150°C Recommended Operating Conditions: Supply Voltage, VCC: 12 ±2V Sync Tip Level: -0.5 to +1.0V Sync, Blanking Level: +1.7 to +8.2V Reg, Green, Blue Inputs (Saturated): 1VP-P Show more
