Can you compare both lists to check if some one has "inserted" himeself in the middle of the queue instead of at the end?

I've checked and all the other lines are ok

Default While waiting......

What is the module's power requirement?
I read on glt's blog that the USB power is being filtered, but I also see a 3V3 header
So is it USB-powered, external powered, or both? Selectable?
If external power is required what is the current draw?

From one of the YouTube videos of the device, I see a drop down menu in the Mac OS control panel for the device where the sample rate is being chosen....
Does that mean that the I2S output sample rate is chosen here, independently of the original sample rate of the file?

Grazie,

Nic

The module is self powered (USB VBUS) in the output connector you have 3.3V from the LDO. For example you can use this pin to know when the cable is plugged.

If you don't like the USB VBUS supply, you can remove the LDO and power the module directly from the 3.3V pin present in the output connector.

About the sample rate menu: In MacOS by default the sample rate is fixed. Audio Midi Setup let you choose the default sample rate. If you want a variable sample rate you need to use a dedicated player.

Thanks!
What is the power consumption from the USB VBUS?
Is the relevant LDO the SOT device seen just below the silkscreen R6 label on the photo you posted?
What is the P3 header for?
What are the DSDOE and TMD.C headers for?
Are these (and the MUTE header) pulled high or low when activated?

The device has an extremely simple interface so I guess I have now run out of questions

Cheers,

Nicolai

Hi Michele,

Thanks for confirming that it wasn't all a dream! Also to Domenico for confirming that I am still due a device.

So it was Jackal29a, eh? Sounds a shady character...

the power consumption is about 600 mW at max speed. LDO near R6 is the right one. P3 is used to erase the flash and force a firmware update via USB.

DSD_OE is 1 when a DSD stream is incoming.

The pin called Mute has been assigned to PIN 11 and is asserted to 1 when a sample rate change is incoming or when there is a stream format change DSD / I2S you can use this pin to avoid noise when the dsd is detected.

The pin 6 is the Master Clock MCLK 22,5792Mhz or 24.576Mhz.

TWC.D is an I2C bus, i m preparing a ConfigTool that let's the user configure Events in the module. For example you can assign I2C address and values to put in the I2C bus when the volume is changing or when a sample rate is changing. blah blah

:-)
Domenico

PS
For each package there is a note with output connector description.

Is it better to power the dsd converter externally, or is usb just fine?

The on-board LDOs are already of very good quality (low noise), but you are free to supply the board by an external supply (Shunt PS? Battery?) with a limited effort. Try by steps, but consider that the starting point is considerably good

Better using an external raw supply rather then rely on the +5V incoming from your computer USB port IMO.
The question is: how can we do that? Should we cut the +5V track from the USB connector and connect the external PS there?
