Not sure if this will help... This is a partial pic of the Sample Rate Systems AC3-RF Demodulator schematic showing the pin out of the PM-4007A. Regards, Dave

Amazing how complicated it really is to convert AC3-RF to S/PDIF. Didn’t really think about what all the legs of the PM-4007A were used for.

Someone posted a PM4007A for sale (old new stock) and we might as well keep the good quality pictures for reference here. Attachment:
