Sony CXD2515Q Datasheet?

Hi Guys,
I been lurking here for a good time and learnt a lot. Now I am about to "rebuild" my old Denon DCD-3000 as a transport - dont know how competitive it might be, but it will be a learning experience in digital audio (Im more used to the analog side). However, I cent find the datasheet for the DSP Sony CXD2515Q anywhere online. I find a 3 page pdf that describes what the numbers on the output means, but thats all. I plan to rebuild the coax S/PDIF output, wich on the original cirquitry seems a bit suspect, but to do that id prefer to have some data on whats actually on the DSP output and not just work in blind...

Hope anyone can help here!
