DESCRIPTION
The STV6411A is a highly integrated I2C bus-con-
trolled 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. It is also fully pin compat-
ible with STV6410A, the three scart version.
