Sample Recommended Oscillator Circuit
R1 = 120 k
R2 = 47 k
C1 = 30 pF
For a crystal oscillator frequency of 16.9344 MHz.
Alternatively:
R1 = 3.3 k
R2 = None
C1 = 5 pF
For a crystal oscillator frequency of 33.8688 MHz.
For an oscillator frequency of 33.8688, the third harmonic is used. This means that
precise component values will be influenced by the printed circuit board. Consult
the manufacturer of the crystal to determine the circuit constants for this frequency.
