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.
