A8520E24A91 – User’s Manual
Release Date 02/27/12
1.2.1. Network Topology and Nomenclature
An A8520E24A91 network consists of one Protocol Master (PM) and one or two Protocol
Slave(s) (PS). The PM provides the audio reference clock and controls network association.
The PS regenerates the audio reference clock based on the packets received. Audio can be
transmitted from the PM to the PS. The device receiving the audio is called an Audio Sink, and
the device sending the audio is called an Audio Source. A device can be both an Audio Sink
and an Audio Source at the same time (bidirectional audio will be supported in future revisions
of the TI PurePath firmware). The A8520E24A91 network also includes a Data Side-Channel
which is a bi-directional data link between the PM and all PSs in the network.
