Description

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.
