Hi,

I am using CC8520 in my wireless audio application. Receiver side i have CC8520 and TLV320AIC3204. I need an I2C master to load registers of 3204. Can I used CC8520 for this. If yes Please Kindly explain how to program this.

    Hi Srinivas, 

    Yes you can. In the PurePath Wireless Configurator tool (http://www.ti.com/tool/purepath-wl-cfg) have a look in the help menu under 'Audio device Definition Files'. It explains how this is done and how you can make modifications or add support for other audio devices.

    Hi kjetil,

                 In my project BCLK and WCLK is generated from codec and mclk of cc8520 is not required by the codec. I choosen external clock in programming of cc8520(External audio interface). The user guide says master clock is wirelessly transmitted. here i am generating clocks externally. how master clock generated inside cc8520. will the system work?

    regards,

    srinivas. T.

    Hi Srinivas,

    The master can either use the internal clock source or an external source. The wireless clock distribution is a way to synchronize the clocks in the slave nodes depending on the clock on the master side. The "synchronization information" will be generated on the master side even when a external clock source is used.

    The slaves on the other hand can only use the internal clock source, since this clock source must be able to be controlled using the "synchronization information".

    Best regards,
    Johan
