Signalyst DSC1

That's a nice project @Paul9334 , very neat.

I need to put together another couple of BBB front ends for DSD decoder projects - are your boards available, either as physical boards or gerbers?
I have PCB and gerber files(power supply,master clock & iso board) , but excluded output board , because it purchase from internet from china .
If you need ,please let me know .
 
I completed PPY's BBB player, I mod circuit diagram & PCB layout ,added master clock selector / power supply board and spdif / optical & IIS over HDMI socket output board ,two clock selected by buffer IC and enable when need, clock using DIP14 socket , all reg. IC upgraded to LT3045. Using PPY's pure firmware. Thanks for PPY.

Very nice!!! Are you feeding the DSC via HDMI "I²S"?

No , BBB output IIS to Soekris DAM1021 R-2R DAC , power amp is Pass Aleph J , all are custom made by my self.

Paul, a question if I may - do you have a mute function for your DACs? I don't see Mute mentioned on the HDMI connections.
I asked seller ,No mute signal cable connect to hdmi socket, I think that you need connect a jumper from pin 11(mute) to hdmi socket by yourself.

My PCB or PPY's PCB included mute output, just mod this output board should be okay.

Dear Paul,
The pcbs and are on their way, I can't wait to have them in my hands.

I am ordering all the components but I cannot find some ic and I would like some advice if possible on the two crystals of the reclock.

The ICs that I can't find anywhere are:
SI8661EC-B-IS1
SI8410BB-D-IS
74HC2G04GW
If you can advise me where to buy them in Europe or alternatives, I would be very grateful.

Thanks and happy Sunday

The oscillators are available from Audiophonics

https://www.audiophonics.fr/en/comp...584-ultra-low-jitter-clock-45mhz-p-14033.html

and the ICs are available from the normal places like Digikey, Mouser or, if you're in the EU, Time but seem to be victims of the global shortage of silicon - maybe check ebay for a local small supplier but expect to pay an inflated price and be less confident about provenance.

Hi Paul, have you tried play BBB (with Pure-Botic) & PPY-recklocker & digital output board also with TOSLINK, SPDIF, AES / EBU or just with I2S output ?
I tried to connect a CD player that has SPDIF and TOSLINK inputs from 44.1 to 192 kHz (16 to 24 bits) with such combination but DAC in CD player
does not recognize any signal.
PPY-recklocker is original (not modified), I try with UPNP and NAA (hqplayer) protocols, Pure version is from 06.12.2020.
Also, I believe that Pure must be set in I2S mode and not in USB or SPDF ?

NB When I use I2S DSC2 DAC, everything works perfectly but only when streaming is DSD signal, of course.
