We can use too 3 HID buttons for setting volume and mute.

Schematics is almost identical to PCM datasheet. Circuit includes these components: Headphone output uses standard 3. First Datashset drill holes for crystal, wires, connectors and buttons. I put circuit on right place, solder one pin in the corner and next solder all pins on second side with thin tin.

Next I solder first side. Effect is, that almost all pins are shorted. Next I must use copper solder wick for draining of tin out. If there are anough colophony that pins automatically unjoin thanks to surface datashet.

These components I solder that after right position I hold them with nail, small screwdriver or tweezer. One pin I solder with small amount of tin. If the component is on the right place, I solder them on the opposite side and finally on the first side. Next I solder SMD connector, wire junctions and finally all components from a top side. Circuit should work immediately after connection to computer. It is seen as standard USB soundcard. For usual operating systems like Linux or Windows XP are not needed any drivers.


It should work too volume settings using buttons. PCB is designed for using only one side with two wire junctions in Eagle 5 application. Almost all components and USB connector are placed from bottom side.

From top side are wire junctions, buttons, inductor, crystal and remaining connectors. I tried to separate analog part from digital and right place ground wires to eliminate interferences.

PCB is designed for easy creating in amateur conditions. There exists too professional variant AES3. Both use same protocol with few exceptions. All three transfer methods have identical signal encoding and we can soever convert between them.

Transfer speed is taken from sample frequency, number of bits and number of channels. Advantage of interface is that only one wire is needed for transferring of complete audio signal. It is simultaneously disadvatage, because receiver must reconstruct clock signal datahseet data datashret PLL and there can rise jitterwhich is heared like a small distortion dstasheet the output of DAC. For transferring of digital audio within equipment is much better I2S bus. I built circuit in two copies and both works on first connection.


Analog output has a good sound without interferences and he is better than usual internal soundcards on PC motherboards.

Low and middle frequencies are perfect, but highes frequencies are a little blurred. Just it isn’t HiFi, but for most people will be quality of sound output sufficient.

This I must more inspect. Schematics and PCB was a little changed. Output impedance will be about 72R. B output from B we leave unconnected. Shield wire we connect with SMD jumper to the ground.

This makes symmetrical output with impedance about R.

Connector is usually XLR with three pins with central third pin connected to the ground. Circuit description Schematics is almost identical to PCM datasheet.
