Maximum XTAL Tolerances Including Temperature and Aging [ppm]
RFM02
Whenever a low frequency error is essential for the application, it is possible to “pull” the crystal to the
accurate frequency by changing the load capacitor value. The widest pulling range can be achieved if the
nominal required load capacitance of the crystal is in the “midrange”, for example 16 pF. The “pull-ability”
of the crystal is defined by its motional capacitance and C0
Note:
• There may be other requirements for the TX carrier accuracy with regards to the requirements as
defined by standards and/or channel separations.
