Hi - in the design it was RA7/OSC1/CKIN with the short trace (9mm, but=20
only 4mm to the xtal pin, the rest to the loading cap), RA6/OSC2/CKOUT=20
on the long trace (19mm).  So if I read the datasheet correctly it is=20
the long trace that is on the output side.  (by random chance, tho it=20
didn't avoid the problems in production for me.)

A good thing to know though.
