Have fun..

Hello,
I'm also interested in this, SPDIF version, but have no great experience with diy. Is there a list somewhere of the steps needed to have it up and running?
Thanks,
Gio

Converter is ready to use.
For all systems Windows , Mac Os, Linux it uses native drivers.
So you connect converter to PC and it should be recognized automatically.
In system it will appear as "Audio device"/"USB->SPDIF V1.0x"

Sorry but at this moment SPDIF version is sold out.
New PCB version soon.

Hi all,

New PCB for USB-I2S version is READY.
Yesterday I sent files to PCB factory, so test pices should be on my desk for 10 days.

Connectors on PCB:
USB - USB bus (type B)
I2S - I2S bus (IDC 2x5pins raster 2.54mm)
POWER - input for external power supply (2x1 pin raster 2.54mm)
JP3 - jumper for selecting USB Bus/External supply, instead jumper you can connect switch(3x1 pin rasetr 1.27mm)
LED - Power LED and Fs LEDs (each Fs has own LED) (6x1pin raster 1.27mm)
J3 -input for external master clock (4x1 pin raster 2.54mm)

Changes compared to the previous version:
-galvanic isolation on PCB (ADUM3160 + LDO)
-shorter track for Master Clock signal (from Xo to TAS1020B)
-elimination of the multiplexer in the Master Clock signal path
-sampling rate signaling with 4 LEDs (each has its own LED)
-series termination resistors on the I2S bus lines
-22.5792/24.5760MHz generators + LDO can be mounted on the PCB, or connected via J3 connector
-additional 16-bit modes for connecting 16-bit DACs such as TDA1541A, TDA1543, etc. (during testing)
-AC-3 passing through mode (during testing)
-derived power to the I2S connector, ability to supply DAC
-smaller dimensions, only 67mm x 30mm
-4 mounting holes

Best regards

Hi All,

I recieved first prototype PCBs (new I2S version, 10pcs, gold plated) and TAS1020B
Tomorrow I will start assembling.

Best regards
