MOTOROLA ANALOG IC DEVICE DATA
The MC13077 is a high quality RGB/YUV to NTSC/PAL encoder with
Composite Video and S–Video 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 MOSAIC
process and
is available in a 20 pin DIP or SOIC package.
