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), S–VHS, RGB, and color difference
(R–Y, B–Y). The composite video can be PAL and/or NTSC as the MC44011
is capable of decoding both systems. Additionally, R–Y and B–Y 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 phase–locked to the
horizontal frequency.
Additional outputs include composite sync, vertical sync, field
identification, luma, burst gate, and horizontal frequency.
Control of the MC44011, and reading of status flags, is via an I2C bus.
Accepts NTSC and PAL Composite Video, S–VHS, RGB, and R–Y, B–Y
Includes Luma and Chroma Filters, Luma Delay Lines, and Sound Traps
