the more I measure on the 3 signals, clock, data, latch
i get more and more confused :
clock demand only one thing : rise times under 20nS, I got 10nS even loaded with a scope.
clock latches data at rising edge, so it makes perfect sense to change data at every falling edge, exactly what rune does.
the latch left/right signal changes at falling edges exactly where data dont care a thing,
so why is the DAC so ultra hysteric ?? add anyting capasitive load to the clock signal and sound get tons of clicks !
I can add 1nF to the latch signal, or even the data signal, no effect on sound, actually the clicks are gone, with just one 1nF cap
on the latch signal, I just cant understand, WHY..
playing hidef audio with 1nF on latch give constant click on left speaker only
this reveal timing is a problem, removing the cap, and I get the "normal" seldom random clicks back,
changed the value to 100pF and now the clicks are gone with 88kHz 32bit mode, and even also DSD
