Page 8: Network Topology And Nomenclature
Release Date 03/26/12 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. -

Page 22: Power Supply Considerations
The A8520E24A91 radio modules have integral noise reduction in the supply line from pins 33 (Vdd) and 32 (IOVdd), consisting of ferrite beads and decoupling capacitances. This arrangement will take care of most supply voltage noise. - Page 23 A8520E24A91 – User’s Manual Page 23 of 34 Release Date 03/26/12 Note that if operated from a battery source there is no need for additional noise reduction. Also note that if the noise source can be synchronized to be off whenever the module is transmitting...
