KKSL Question
May 10, 2012 00:00

SigmaDSP is running at 48K

SPDIF IN data rate is 96K

External DAC is set for 196K

ASRC establishes smooth data flow between all these? Is that what it means? Or is there something more to it? Or is it something else?

Thanks in advance!!

Hi KKSL,

Yes, that's correct. If you were to simply transfer the data without changing the clock rate, you would experience distortion and other signal integrity issues. The ASRCs are required to transfer data between different clock domains.
