Someone please name a good USB digital audio transciever. The T-I PCM2906 seems like a good candidate, but neither Digi-key nor Allied nor Newark have any. Digi-key is quoting March for more stock!
I'd like to build a simple USB device with four digital outputs: AES/EBU, coax S/PDIF, optical S/PDIF, and I<sup>2</sup>S over LVDS. The device will be powered by the USB line.
I know Philips makes USB audio interfaces, but I can't figure out which are the ones I want, and where I can get them.
Other chips in the design will be TI DIR1704 for low jitter conversion of S/PDIF to serial audio, and CS8420 (I have spares laying around) for the AES transmitter.

Hi jwb
I will use tas1020a from texas instruments.

As soon as i get usb connector, i will make a board to see what happens, when i connect it to pc.
I do not know, how can i made tas1020a output i2s (with eprom conected to it or from pc).
Good luck,
Aleksander

Windows got drivers for USB audio since Wiruz98 i think atleast i didnt need any new software for my PCM2702based dac. Works really god and kicks my AC97 onboard soundcard ...
Just make sure that the settings is for a continius data flow for optimal performance..

When I connect tas1020 to computer windows xp does not recognize it. It is unknown device.
I need application code for tas1020b and DFU ( i guess this is program from ti for configuring tas1020 via usb).
If someone have this, please let me know.
Thank you in advance

Hi jwb,
Philips devices:

They are dip devices with i2s output.
If anyone knows, where to get them, please let me know
