Default Marco I am interested in USBPAL

Marco,
Please let me know how to arrange getting the USBPAL from you.
Thanks,

This signal can be generated from the ENABLE pins on either the 22.5792 MHz or 24.576 MHz clocks.
Hi deanoUK. Thanks for pointing me to this thread.

Have you successfully completed your USBStreamer/Cronus project? As I am interested in doing the same.

Are you using 45/49 clocks on the Cronus or 22/24?

Isn't Pin 4 of the CS2300 chip attached to MCLK OUT? So there would be more to macking it MCLK IN than simply removing the one resistor?

Could you also please provide details on which are the enable pins on the clocks?

Thanks in advance!

Russ, Is it possible to halve the MCLK out of the Cronus back to the USBStreamer? In which case am I better off with the 49/45 Rhea Modules to pair a USBStreamer with a B3?

This would get you 8 isolated/reclocked channels all sharing the same cronus master clock. If you need more help let me know.
Hello Russ

I have one Buffalo II+Cronus+Amanero for normal two channel operation.
Now i want to add another Buffalo for a 4 channel projekt.
For that i want to use the minidsp usbstreamer. Can you advise me how to connect the Cronus (isolatet)to the usbstreamer ? Hermes-Amanero is only for two channel operation right ? Can Hermes-BBB do the job and when how can i connect it ? The next problem hermes-BBB boards are out of stock. Is there
any chance to become one board ?

Thanks
Udo

There's a bit more to it than Russ suggests. The Hermes BBB requires control and clock select signals as well as just data. I gave up on the project and just used the cronos to reclock the usbstreamer.

If you really want to isolate the usb streamer its probably easier to construct your own simple circuit using a couple of the same potato flip-flops wired up to the cronos (cronos has a clock selection pin you need to be aware of btw).

If you don't need isolation and you dont intend running the DAC in slave mode off of the Cronos I would use the DIYINHK multichannel board rather than the USBStreamer. It doesn't have the same clock issue and it uses the newer xcore200 chip.

Hmm, ok. Do you desolder the resistor near the Xmos Chip to extract the MCLK signal for CS and feed in the new reclocket signal from cronos here ?

You mean without cronos and BIII in mastermode ?
