General DescriptionThe STV6688 is a highly-integrated I²C bus-
controlled 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 microcontroller provides a
CVBS signal for an external device (monitor).
