TomY Question

Jan 30, 2019 00:00

Hi,

I find that the fs rate can select 384fs/768fs in SigmaStudio as follows.

However, I believe that Serial Port and ASRC of ADAU1452 is Max 192kHz.
-Serial Port FS Max 192kHz
-ASRC I/O Sample Rate Max 192kHz

Is it possible to support 384fs/768fs by ADAU1452 or other SigmaDSP?

Do you have any solution for 384fs/768fs?

Best regards, TomY

Hello TomY,

This is for other parts that SigmaStudio supports that have a higher rate.

However, By creative use of serial ports, and writing a custom program, you can interleave data between several serial ports to end up with a faster data throughput but it is not easy to do. Ken had done some experiments but so far we do not have any kind of applications notes about it nor have we tested this to any great extent.

Hi, Dave

Thank you for your reply.
I understood that currently it is not realistic to support 384fs/768fs.
