SAA7000 chipset

Thank you for the link.

I've looked at the data and determined that the SAA7020 in this Marantz is the last IC in the lineup which is passing data.

The error output is staying low while the data output shows data timed with the data latch output and also in time with the frame strobe.

All of this appears at the correct pins on the inputs of the SAA7000 but nothing is appearing on its outputs. The SAA7030 is sitting around clocking its offset into the DACs and all else looks normal.

Is anyone familiar with this happening? I'm guessing the sAA7000 is not working properly?
