Notes
1. Crystals that meet this specification include: Ecliptek ECX-5788-13.500M,Siward XTL001050A-13.5-14-400, Raltron A-13.500-14-CL,PDI HA13500XFSA14XC.
2. –115/+115 ppm assumes 2.5 pF of additional board level load capacitance. This range will be shifted down with more board capacitance or shifted up with less board
capacitance.
