... AT Parallel The CY28443-3 requires a Parallel Resonance Crystal. Substituting a series resonance crystal will cause the CY28443-3 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. Crystal Loading Crystal loading plays a critical role in achieving low ppm perfor- mance ...
