Hi,
In the AM1808 data sheet, section 6.11.3.11, the requirement no. 1 "Center to Center CK-CKN Spacing" is given as max. 2w, where w is w = PCB trace width as defined in Table 6-27. Note 2 adds that "Center to center spacing is allowed to fall to minimum (w) for up to 500 mils of routed length to accommodate BGA escape and routing congestion.".
So my question is: If center to center spacing may fall down to w, and w is the width of both traces, wouldn't that result in a short circuit?
Could you please help me to understand these specifications?
Regards, Christian
