Hello Jarek,
i have just finished my little DAC project with your USB/I2S converter and it is working very good. I am running a headless Intel D510MO-Board with Voyage MPD. The D/A-Converter is a PCM1794 COD board from twistedpearaudio.com, I/V-conversion is done by 33 Ohm resistors and little transformers from South Korea. I am very satisfied with this solution. Good work Jarek!

Have a nice day
Martin

Hi,

New version of USB-SPDIF PCB is finished.

Changes compared to the previous version:
-galvanic isolation on PCB (ADUM3160 + LDO)
-shorter track for Master Clock signal (from XOs 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 connector
-two modes: 16 bit (32bitframe-16bit data) and 24 bit (32 bit frame-24bit data)
-LEDs and power switch on the front side , connector on the back side
-4 mounting holes
- S/PDIF Output: COAX, TOSLINK, AES/EBU

First prototypes PCBs (5pcs) in production.

A also ordered next batch (10 pcs) of PCB for USB-I2S converter.
If any one is interested in it will be available in early March.

In attachment pictures of PCB, both versions USB-I2S and USB-S/PDIF.

Best regards

I can't find a power adapter plug that fits with the first version does anyon know the size of the male pin for the power supply jack?

JarekC · 21st February 2013, 11:07 AM

Old version (6107 PCB): Power Plug 5.5mm/2.1mm
Newversion (6117 PCB): Power Plug 4.5mm/1.3mm

For example:
Connectors, Interconnects | Barrel - Power Connectors | DigiKey
