Datasheet for CDM9 / CDM9 Pro

Hi.

I've a micromega microdrive, and i want to make a DIY konverter for this drive.

The mechanism should be a CDM9 or CDM9 pro, but i'm not able to find any datasheets on this. Can anyobe help me ??

I'm planning to use the I2S (if it is present) and place the clock in the converter in order to minimize the jitter.

The converter will probably a TDA1543 without oversampling.
