(reposting) L-Train's 96KHz SNES SPDIF PCB on Jaguar

Recommended Posts



I had the idea of using this PCB to implement a "normalized" SPDIF output on the Jaguar, but after looking at the SRC4192's datasheet, I'm a little confused as to how it works and whether it would work with the Jaguar's variety of oddball sample rates.


Would any of the more technically-minded of you be able to comment on this?

From a quick glance, the SRC4192 seems to support any input sample rate from 4 to 212 kHz, so it looks like it should work.


However the digital audio input format is different: the SNES appears to use 16-bit right-justified, while the Jaguar uses 16-bit I²S. The latter is not supported by the SRC4192. So you'd have to add a bit of logic to do the conversion.


You should also ask the guy who made the board to get his opinion.

Is there any kind of simple "word length converter" IC available? I haven't been able to find anything with a quick search.


EDIT: According to this guy, the converter does work with 16-bit i2s despite its absence from the datasheet. Weird. http://www.diyaudio.com/forums/digital-source/240007-16bit-i2s-48khz-source-src4192.html

Thanks! I ordered the components (including a new Jaguar), so I should be able to test this in a couple of weeks or so.


By the way, unrelated question: if you've ever had your hands on the official Jaguar SCART cables, do they use injection molded connectors for the console end? I just bought one that I was going to modify for composite sync, and I'm worried I made a horrible mistake.
