STV6688, Video Switch Matrix

The STV6688 is a highly-integrated I²C buscontrolled video switch matrix, optimized for use in color TV applications.

It is used to control the switching of 4 video signals.

These signals can be in Single Component form (CVBS) or in Two Component form (Y/C).

In both cases, the STV6688 microcontrolle
