  • The STV6417 is a highly integrated I2C bus-controlled audio and video switch matrix, optimized for use in digital set-top box applications. It provides all the audio and video routings required in a full two-SCART set-top box design.

    The STV6417 is a fully integrated solution for filtering and buffering SD signals
