Carte Allo DigiOne – essai et comparatifs

A new DigiOne (signature) is coming soon
Improvements
1 Clocks are changed to NDK SDA (lower jitter)
2. All important bypass capacitors are now film
3. 2 power inputs , one for “dirty side” and one for “clean side” . Dirty side input is 5V (2.5A for RPI) and clean side 5-18V (75ma) allowing even batteries to be used
4. Clean side has now a supercap for plenty of power on board.


We are measuring less than 400fs of jitter on the buffer.
However every noise measured on the system has come down. Every buffer , flip flop noise is now measured in uV instead of mV.
I am very confident that in most systems you will hear a difference.
Also note that now DigiOne is made out of 2 boards , one is for “dirty side” and one for “clean side”. In fact we increase the size of the PCB about 220%
With all the extra space we were able to add lots of capacitance, filters etc that make the noise in every rail to decrease . (in some cases dramatically )
At last , using batteries you are making the “clean side” galvanically isolated from the mains. That can make big difference for some systems

a voir le nouveau tarif, la nouvelle taille effective et si il y a une amélioration.
je suis dubitatif sur l'ajout d'une super capacité sur le "clean side" on ne devrait pas avoir besoin de bcp d'énergie de réserve.
