I have finally found the IIS pads on the Empeg MK 2 board. Now the question is how to go from IIS to the inputs on a CS8405 chip for purposes of an SPDIF output on the Empeg. What circuitry is needed to take the IIS output and interface with the serial data and word rate clock inouts on the CS8405? What do each of the 5 pads do on the Empeg (see attachment)? If I can figure this out, I am going to be building an add on SPDIF output board for my Rio Car.
