... Crystal Recommendations The CY28RS480-1 requires a parallel resonance crystal. Substituting a series resonance crystal will cause the CY28RS480-1 to operate at the wrong frequency and violate the ppm specification. For most applications there is a 300-ppm frequency shift between series and parallel crystals due to incorrect loading. ...
