Sample Recommended Oscillator Circuit
R1 = 120 kΩ
R2 = 47 Ω
C1 = 30 pF
Crystal oscillator frequencies: XTALCK0 = 16.9344 MHZ and XTALCK1 = 20 MHz
or:
R1 = 3.3 kΩ
R2 = None
C1 = 5 pF
Crystal oscillator frequency: XTALCK0 = 33.8688 MHz
If third harmonic overtones appear when using a 33.8688 MHz frequency with the
recommended circuit example, consult with the manufacturer of the crystal
element, since detailed values of the circuit constants will be influenced by the
printed circuit board.
