Crystal Recommendations
The CY28410 requires a Parallel Resonance Crystal. Substi-
tuting a series resonance crystal will cause the CY28410 to
operate at the wrong frequency and \violate the ppm specifi-
cation. For most applications there is a 300ppm 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. To realize low ppm performance, the total capacitance
the crystal will see must be considered to calculate the appro-
priate capacitive loading (CL).
The following diagram shows a typical crystal configuration
using the two trim capacitors. An important clarification for the
following discussion is that the trim capacitors are in series
with the crystal not parallel. It’s a common misconception that
load capacitors are in parallel with the crystal and should be
approximately equal to the load capacitance of the crystal.
This is not true.
