DESCRIPTION

The STV6411A is a highly integrated I2C bus-con­trolled aud io and vid eo sw it c h ma trix , opt im iz ed for
use in dig ital set-top bo x app licatio ns. I t prov ides all
the audio and video routings required in a full two
scart set- top box des ign. It is also fully pin compa t­ible with S TV 6410A, the three sc ar t ver sion.
