Forum Post: RE: 66AK2H12 unused input clocks

Hi Bill,

An another topic, we followed the Eval board schematic for the quantity and values of bulk and bypass capacitors, and ferrite bead filters.     However, the H/W Guide includes quite a few more and larger capacitors (Table 3).  E.g. there are 8 1500uF caps  (p/n T530X158M2R5ATE005) for CVDD and 4 for DVDD15.    We only have 1 each.      

Did you find problems where the Eval board didn't work because of this?   Again, we can't really change our current design now, especially the large capacitors, until our re-spin.   So bottomline:  can we expect our design to work?

thanks,   Scott
