Allo Katana DAC

Hi Bryce,

The setting that the Katana driver exposes if DoP ON/OFF.

Whats DoP sync/async? Do you have a link that explains the feature?

Hi Tim, 

Sync/async is an ess9038q2m parameter. I was not able to find a good link that describes the feature, but it is discussed on some of the diyaudio forums. In looking for the link I found the answer to my question in a post from cdsgames: 

Enter Synch mode with Katana. Why use dPLL at all on ess9038q2m ? Our clocks are clean so we use a little trick called SYNCH mode where dPLL is bypassed . Direct clocks no added sauce . Dpll setting = 0

Makes sense right ? Hold on, electronics are never simple. Enter DOP. DOP is not supported in synch mode.

Behind the scenes we implemented a very sophisticated driver that sw betwen asynch (dop) and synch (pcm). 

So it seems that DoP ON/OFF also switches sync/async.

Cheers.
