The Motorola MC44011, a member of the MC44000 Chroma 4 family, is designed to provide RGB or YUV outputs from a variety of inputs. The inputs can be composite video (two inputs), SVHS, RGB, and color difference (RY, BY). The composite video can be PAL and/or NTSC as the MC44011 is capable of decoding both systems. Additionally, RY and BY outputs and inputs are provided for use with a delay line where needed. Sync separators are provided at all video inputs. In addition, the MC44011 provides a sampling clock output for use by a subsequent triple A/D converter system which digitizes the RGB/YUV outputs. The sampling clock (6.0 to 40 MHz) is phaselocked to the horizontal frequency.
