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 × 10 × 1.4 mm) package, the STV6414A is compatible with the STV6413.
