Cross-talk from Clock to ATWD Channel 0

Symptoms:

here appears to be coupling from the clock waveform, when it is muxed into ATWD ch3, into channel 0.  Looks like the oscillations are about 1mV in channel 0.  Kael mentioned this was a known issue in earlier mainboard revs, but I wanted to make sure you guys knew that it was still around.

Approach:

Investigate with Rev 5.0 DOM MB whether the symptom still exists.  Determine whether the symptom must be eliminated by an apropriate configuration, or if  some other revision is necessary.

Solution:

TBD
