■

Blu-ray and DVD players

Description

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.
