Description

The STV6413 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 a TQFP64 (10 x 10 mm) package, the STV6413 is compatible with the STV6412A (TQFP64 14 x 14 mm) used for designing boards with two levels of integration.
