Features, Applications

The is a high quality RGB/YUV to NTSC/PAL encoder with Composite Video and S­Video outputs. The IC integrates the color difference and luma matrix circuitry, chroma modulators, subcarrier oscillator, and logic circuitry to encode component video into a composite video signal compatible with the NTSC/PAL standards. The IC operates off a standard 5.0 V supply and typically requires less than 75 mA, making it useful in PC environments. The high degree of integration saves board space and cost, as only passive external components are required for operation. The IC is manufactured using Motorola's MOSAICTM process and is available a 20 pin DIP or SOIC package. Single 5.0 V Supply
