STV6418 Audio/video switch and 6-channel SD/PS/HD video filter
The STV6418 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 STV6418 provides fully integrated solutions for filtering and buffering both SD and HD signals.
