AM6528: Audio codec

Mohsen Khayami

Part Number: AM6528
Other Parts Discussed in Thread: TLV320AIC3106

I am trying to find out what do you recommend for Audio codec (1 speaker and 1 microphone) to connect to AM6528? I assume it should be connected to the McASP.. If we have reference design or any documentation would be great.

It would be great to recommend a device that we have the driver for it already.

Thanks

Mohsen,

What SW is your customer using? Is it Linux or RTOS?

Mohsen,

You can find the codec drivers in Linux under sound/soc/codecs. This is where you would find the aic3106 driver for example. Many of these are I2S based and can work similar to the 3106.

I hope this is helpful to you.

Thanks for the post.

Hi Mohsen,

We have an internal AM65x board with AIC3106 populated. If you need slightly cheaper device, the AIC3104 is about 25 cents cheaper, and equivalent. The same software should work for both.

Some resources on the software side:
