The TSB43CA43A content-protected (5C) and TSB43CB43A (non-5C)
are highly integrated 1394 audio solutions that enable a simple
one-cable digital connection between audio components. Audio over
1394 can support high sample rates, multiple channels, and even 5C
streaming between a DVD-Audio/SACD player and an AV receiver.
