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.
