RGB ENCODER
MB3514
The MB3514 is an RGB encoder that receives analog RGB and composite
synchronous signals and outputs NTSC and PAL composite video signals. Y
(luminance) and C (chrominance) signals and analog RGB signals can also be
output.
The MB3514 incorporates a matrix circuit, balanced modulator, and Y-C signal
mixer for RGB signals. It generates various signals required for encoding, which
makes it suitable for personal computers.
