PurePath™ Wireless Audio
CC8520
The CC8520 is used to build a lossless
wireless audio link. One CC8520 acts
as audio source and the other as
audio sink. I
2
S data is taken as input
on the audio source side, audio data
is transmitted without loss to the audio
sink which then outputs the I
2
S
audio data.
