encoder with audio digital inputs

Post by gerolamo » Mon 2016-03-07 17:56

Dear Support,

We have already used your VS1053 and VS1063 encoder/decoder chips in our products.
For a new application we need an encoder with audio digital inputs instead of the analog ones.

Could it be possible to use one of your chips for this kind of application?

Regards

Gerolamo

What kind of digital input you have?

Can your controller receive the data and send it to vs1063a for encoding? If the answer is yes, take a look at the SDI Encoder application from http://www.vlsi.fi/en/support/software/ ... tions.html . You can send PCM data through the serial data interface, and read the encoded version through SCI (or UART).

Pasi,
Thanks for your answer.
It seems it could be useful for our application.

Hello Gerolamo,

depending on your application, you might also want to have a look at the VS1005 family. There we have digital inputs like I2S and S/PDIF (driver for S/PDIF still pending though), plus interfaces like SD card read/write and USB. As VS1005 is a system-on-chip, it can have much more functionality than VS1053/VS1063.

Kind regards,

Hello Henrik,

Thanks for for the additional support.
I am now testing the VS1063 encoder with the digital inputs.
If it works as expected it is better for our application than the VS1005, since we don't need the additional functionalities of the Vs1005.

Kind regards

Gerolamo
