Crystal Recommendations
The CY28419 requires a Parallel Resonance Crystal.
Substituting a series resonance crystal will cause the
CY28419 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.
