 +1 Good Answer/Helpful		 #131805 - where did you measure?
Responding to: ???'s previous message
Did you measure those traces touching directly the clock and data pins on the MAX?
If not, you should do so.
Also, you should measure ground connection directly pin-to-pin. Same for VCC and maybe other pins which might be of interest...
