Default 192kHz S/PDIF coaxial input on budget?

Hi,

I'm looking for a sound card capable of 192kHz over S/PDIF or AES/EBU.
PCI is welcome.

I need it to connect PCM4222EVM for THD/FR measurements...
It should lock on external clock, derived from received S/PDIF...


All i am able to find are cards with 96kHz inputs.

I already have the following cards, which are 96kHz limited:
- E-MU 0404PCI
- M-Audio Audiophile FireWire
- M-Audio Revolution 7.1
- Terratec Aureon Space 7.1

Thanks!

All Envy24-based cards with the MIO/DIO addon card (Audiotrak Prodigy 192, MAYA44 MkII, Waveterminal 192)

ESI Juli@

Infrasonic Quartet

Hehe, too bad i already have 3 Envy24 cards, none of which has the MIO/DIO connector

Envy24 chipset doesn't have inbuilt support of SPDIF input of 24/192. They require additional MIO/DIO cards as you stated.
Although these cards go for cheap over eBay, they don't have the MIO/DIO card included with them, and MIODIO cards cost as much as used Envy24 card... Unobtainable too.

ESI Juli@ is nice, but pricey even in used condition... Analog IO is overkill for my applications.
Infrasonic Quartet - can't find it on eBay.

I have found out, that CMI-8788 based cards do support 192kHz input, as their chipset have these inputs by default.
I'll try to get the Auzentech X-Meridian 7.1.
There is some BGears B-Enspirer card with this CMI chip too, but it has TosLink I/O only. Probably it could be modded to take coax tho...

Thanks!

CMI-8788 cards are fine too.

CMI-8788 - usually only the ones with coax SPDIF can do 192kHz...

But wouldn't there be bad reflections of the digital signal caused by that breakout cable???

The cable is bit-perfect :-) And that is all you need for recording from spdif input. Timing/jitter is no issue in this case since the recovered clock from SPDIF input does not control any DA conversion farther down the stream.

I was thinking in terms of using this card as an output, not an input.
In this case I think the reflections would be an issue?
