I'm interested in tapping internal I2S outputs from working soundcards&syths with outdated analog sections and exporting their output to S/PDIF, rather than SPDIF to I2S (see http://linuxaudio.org/mailarchive/lau/2010/6/25/170787 ). I was excited to find that this module was cheaper than the $200.00 WM8804 evaluation board that appears to be able to perform this task, but less enthusiastic after clicking on the "transceiver" link and landing on the "S/PDIF receiver" link instead.

Is there a way to enable the other direction of signalling -- I2S->S/PDIF -- on this "S/PDIF receiver" board?
Or do I need to the Wolfson WM8804-6152-DS20-EV1 board ( http://www.mouser.com/ProductDetail/Wolfson-Microelectronics/WM8804-6152-DS20-EV1/?qs=Xqu1B/s4UobSmDPf34PglA%3d%3d )

Another alternative is to find a hard to find and overpriced Toshiba TC9231N ( http://pdfserv.datasheetpro.net/ToshibaSemiconductor/TC9231N.pdf -- $76.00 just for the chip ) using a circuit like http://gamesx.com/wiki/doku.php?id=av%3Anintendogcda
but using a 11.2896Mhz xtal for 44.1K instead of a 12.288Mhz crystal for 48K rate of Nintendo box from above link.

Other older devices interfaced similarly include a Roland SoundCanvas SC88 and a Yamaha MU-10:
