Further ESS Sabre DPLL Tweaking

I don’t know if there is a well defined direct correlation, but this setting gave me a pretty stable lock with DPLL set at “LOW” with the Musiland USB -> I2S. I am pretty happy with the performance of this USB interface so far.

Seems ESS designed the DPLL with low enough bandwidth to be a good experimental gauge of jitter for even the big league USB interfaces.

I can probably do a more scientific experiment by wiring the lock LED to an arduino interrupt pin and count the unlocks within a period of hrs…
