I am working on an adaptation of the new Arduino Due board and I cannot figure out what are the types of crystals it uses. Specifically Y1 and Y2 in the schematic. Does anybody have the reference for those?

Thanks in advance,

mantoui

From the schematic/bom
   Y1,12MHz KX-7 20pF     CRYSTAL-3.2-2.5           CRYSTAL-3.2-2.5  probably 30ppm
   Y2,32.768Khz,RESONATOR_EPSON_FC_145,RESONATOR_EPSON_FC_145   20ppm 12.5pf

I did some frequency checks using NTP-host and/or GPS pps, see
