Description
The STV6419 is a highly integrated I²C bus-
controlled audio and video switch matrix,
optimized for use in digital set-top box or DVD
recorder applications. It provides the audio and
video routings (CVBS and RGB) required in a
non-full two SCART set-top box design.
The STV6419 is a fully integrated solution for
filtering and buffering SD signals.
