TDK 5100 F
Preliminary
Wireless Components
Target Specification, July 2003
Example for the FSK-Mode:
FSK modulation is achieved by switching the load capacitance of the crystal as
shown below.
The frequency deviation of the crystal oscillator is multiplied with the divider
factor N of the Phase Locked Loop to the output of the power amplifier. In case
of small frequency deviations (up to +/- 1000 ppm), the two desired load
capacitances can be calculated with the formula below.

Because of the inductive part of the TDK 5100 F, these values must be cor-
rected by Formula 1. The value of Cv± can be calculated.
