Order this document by MC1377/D MC1377 Color Television RGB to PAL/NTSC Encoder The MC1377 will generate a composite video from baseband red, green, blue, and sync inputs. On board features include: a color subcarrier oscillator; voltage controlled 90° phase shifter; two double sideband suppressed carrier (DSBSC) chroma modulators; and RGB input matrices with blanking level clamps. Such features permit system design with few external components and accordingly, system performance comparable to studio equipment with external components common in receiver systems. · Self­contained or Externally Driven Reference Oscillator COLOR TELEVISION RGB to PAL/NTSC ENCODER SEMICONDUCTOR TECHNICAL DATA · · · Chroma Axes, Nominally 90° (±5°), are Optionally Trimable PAL/NTSC Compatible Internal 8.2 V Regulator 20 1 P SUFFIX PLASTIC PACKAGE CASE 738 20 1 DW SUFFIX PLASTIC PACKAGE CASE 751D (SO­20L) ORDERING INFORMATION Device MC1377DW MC1377P Operating Temperature Range TA = 0° to +70°C Package SO­20L Plastic DIP Figure 1.
