Description
The STV6414A is a highly integrated I²C bus-
controlled audio and video switch matrix,
optimized for use in digital set-top box
applications. It provides the audio and video
routings required in a two SCART set-top box
design.
In an LQFP64 (10 Ã 10 Ã 1.4 mm) package, the
STV6414A is compatible with the STV6413.
