At this point we have established that all slave TI DACs use BCK from RPI---going to PLL---feeding the DAC SCK.
PLL has jitters and so does BCK from RPI
I am unsure on how the 2 jitters are adding...can anyone answer ?

Hi !
Have same question here.
My linear power supply climbs up to 5.6V and I'm worrying about frying it.
Is there a max admissible voltage ?
My kali....running on my akm board...
After 5 songs.... i have to say i m very impressed with sound quality!

5.5v max into the Kali.

@Greg
Thank you ! Have not seen this.
Would be easier if written in clear in Kali technical manual.
@Pistollero
I'm glad you like it also. Kali+AK seems to be a very nice combo.

We are using TI LDOs LP5907 LP5907 | Single Channel LDO | Linear Regulator (LDO) | Description & parametrics
SPDIF
...achievement, *unlocked* 😛
I give you one standard hifiberry digi+
* forced into hardware config mode
* set to slave mode in hardware
* kali MCLK pin29 --> digi+ MCLK pin36
All with jumpers 🙂
sitting & working on the the kali (using the generic ES9023 driver)
( it did take an oscilloscope to slowly figure this out, the wm8804 datasheet & pin layout. What can I say, was bored this morning )
It's playing music!
Now to see if it's worthwhile (don't now if PLL still involved, all that crap) BTW, this is one of the buggy kali192's
(signals look crappy 'cause resolution goes down on the scope the more channels you use... can't get the full 1Gig samples/sec)
channel4 is spdif, then continues on to a Dac, listening now:

Are you taking the outputs directly from the Aout + pins on the chip, and through the MCaps? No other R/C filtering?
...more re: kali <--> digi+
verrrry sensitive to the MCLK jumper, just tap it all kinds of interesting distortion-- will need to change that. No wonder Ioan added a U.FL connector for that underneath.
notice the digi+ running without its always on green LED, maybe that's set on with the driver, interesting.
that orange GPIO LED is just set on by squeezelite, just something I do

Thanks Greg!
Didn't even expect to make that post, but it lit up & worked...! 🙂
Will follow up on sound quality. See if it's a go or not.
Kinda cool, huh... set a few pins low, jumper the clock over. So simplistic once you are there.

Feels good to remove things 😉 no need for that buzzing 27Mhz onboard crystal anymore:

I'm guessing removing crystals means you like it?
BTW, love your choice of music... LOVE early Metheny!!!

@cdsgames
I second bismuth's request, it's impossible (without extra circuit / software hacks) to enjoy a movie or play a game with the latency present.
Also, AFAIK none of the existing reclockers have this functionality implemented, this could be your unique feature.
