Overview
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.
