... RGB Encoder Description The CXA2075M is an encoder IC that converts analog RGB signals to a composite video signal. This IC has various pulse generators necessary for encoding. Composite video outputs and Y/C outputs for the S terminal are obtained just by inputting composite sync, subcarrier and analog RGB signals. ...
