NOTES: 1. Devices should not be operated at these limits. The "Recommended Operating Conditions" table
provides for actual device operation.
2. ESD data available upon request.DescriptionThe 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.
Additional outputs of MC44011 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.
