USB ASIO interface

Alvis Chan

Hello,

I have a project need to make a USB ASIO interface for audio signal capture and generation. Requirements as below. Any suggestion will be appreciated.

1. At least 2 input and 2 output, 8 in and 8 out is also welcome. IIS or SPDIF both OK.

2. USB interface.

3. One to two chip solution, easy to use is welcome. Maybe a codec plus a AD/DA chip?

4. SNR for the AD/DA at least 110dB per channel.

Thanks.

Alvis,

As a starting point, could you please take a look at the C55x product page? There are several flavors of the device available.

http://www.ti.com/lsds/ti/processors/dsp/c5000_dsp/c55x/overview.page

We typically recommend the http://www.ti.com/product/TLV320AIC3204 codec, as this is used in our C55x EVMs.

Would also recommend taking a look at the connected audio Framework http://www.ti.com/tool/C55X-AUDIOFRAMEWORK & http://processors.wiki.ti.com/index.php/C5000_Connected_Audio_Framework

Hope this helps in moving in the right direction.
