3.0 AUDIO TRANSCEIVER
SOLUTION
Microchip's Audio Transceiver (AT) solution enables
Bluetooth capability in non-Bluetooth Audio-
equipment. The AT receives audio inputs through Aux-
in or I
2
S pin and streams the audio up to two Bluetooth
paired sink devices.
The AT solution can work as either an A2DP source or
A2DP/HFP sink (where BM83 is a sink device).
The following figure illustrates a typical example of an
audio transmitter taking input from Aux-in and
transmitting the signal to two connected sink devices.

S as input and transmitting to
two connected sink devices.
