Title: SPDIF limit of 96KHz ??? Post by: ivo on February 20, 2010, 12:18:31 am Was browsing the web for i2s, spdif, usb and transformations amongst them while I accidentally found out the following on http://www.zerooneaudio.com/faqs.htm:
Quote Yes. The Ti48 also has an S/PDIF digital output. The data sampling rate will be limited to 24 bits/96kHz via S/PDIF as this is the limit of the S/PDIF standard (whereas the Zero One Audio I2S data transfer allows a sampling rate of up to 24 bits/192kHz to be sent to the Ar38). Can someone comment on this? I did read SPDIF standard, but could not find anything of the sort there. Maybe I have missed something??? Title: Re: SPDIF limit of 96KHz ???

http://www.tnt-audio.com/sorgenti/zero-one_e.html 24 bits/96kHz via S/PDIF is the limit of the S/PDIF standard -->> I think this is BS, SPDIF standard can do 24/192 too, the TI48 however maybe not QUOTE: The sound card is only used to extract the digital audio from either the DVD-ROM or HDDs. From the sound card, the signal is sent via the Zero One custom 24/192 I^2S cable to the DAC. I^2S is a Philips proprietary data transmission protocol, also used by Accuphase whose implementation is rumoured to use a shared clock. Zero One's separate clock technology should enable a genuine 24bit 192kHz transmission by interleaving two 24bit 96kHz channels. It may seem strange for a start-up company to adopt an uncommon interface standard in its first product, but it gives them absolute design freedom to optimise every link in the data chain to match their particular needs rather than bodge to fit existing audio technology. The I^2S output is supplemented by a S/PDIF coaxial (RCA) and a TOSLink optical inputs & outputs but these would prevent use of the Ti48 features that make it unique, so they're superfluous.

It will be the quality of the cabling and all that state the limits.
Of course you are dealing with (receiver) chips and their processing capacity or "something" in the chain which just wasn't made for the higher speed. On that matter things just change throughout the years ... |
