Keeping the signals always aligned with the clocks. I recalled your words. Thank you.
I'm guessing that I'd need a new firmware chip for a DPLL change?
Fortunately, upon replacement of L3 ferrite beads, all is back to the previous excellent performance [emoji41].
OK, no more synchronous BII talk from me in this thread. [emoji56]
Hi Russ,
What kind of playback software can support the Hermes-BBB/Cronus cape for BeagleBone Black and how about any remote control client sofeware I can use to navigate my music library currently sitting on a NAS ? Can squeezelite be installed or already included in the Botic software ?
Thanks

Botic comes with ympd and you can use any mpd app on your phone for remote control, but you can build a Squeezelite version by following the instructions here:

Hey Russ -- any chance that you'll produce a run of these Teleporter adapter boards? I'm definitely interested in one for my setup where I'll be running Cronus -> Teleporter -> I2S via HDMI.
I'd guess there's no disadvantage to powering the Teleporter from Cronus vs it's own dedicated regulator? And there's probably an advantage of doing a direct board connection from Cronus to Teleporter.
SDIF connection, revisited
Hi there,
Besides B3 and B3SE, I’m an avid user of Stereo 192 DSD Dac from Mytek. The mastering version of this Dac has DSD inputs for SDIF signals (BNC) on the rear panel and I’ve already confirmed there was no problem with SDIF (both of SDIF-raw and SDIF-3) connection to it from BBB with Botic drivers as posted before.
This time, I set up the same SDIF connection of DSD128 sources to the Mytek via the Cronus board taking an advantage of ready-to-use uFl housing which can provide easy SMA-BNC conversion of D1 to DSDL (left) and D2 to DSDR (right) as shown in the first figure.
The word clock was obtained from DCK by a pair of clock dividers (ICS542 from IDT) with 5V/3.3V conversion from the VD on the board as shown in the figures. The result was quite satisfactory and I could enjoy the stable sound of DSD128 under rock-solid locking of signals.
This may be a rather anomalous use of Hermes/Cronus boards but I’m quite happy with the results. Any comments, particularly on the possibility of uFl-BNC impedance mismatch or selection of WCK sources (MCK or BCK?) will be appreciated.

Excellent! I am very glad it suited your purposes nicely.
As to impedance - they should be close enough as to not create any significant issues at all. Your scope shots look great!
Hi Russ,
Many thanks for your kind words. Appreciated very much. BTW, I always use a 75Ω terminator at the other end of WCK cable.
So to connect BIIISE to Cronus we just use headers, we dont remove XO Trident, we dont remove BIIISE clock. Is that correct? In case of Dual Mono BIIISE what is the connection strategy?
You must always remove the XO trident if you use an external clock. You don't do anything with the XO itself - leave it alone.
For dual mono with B3 or B3SE I would suggestion async mode (just leave Buf configured normally with XO trident) - but if you go synch you need to route the master clock to both DACs.
In any case for dual mono you just route all signals (except MCK if going async) to both DACs.
