Third-Overtone Crystal Oscillator External Circuit
CX24118A
40 MHz sinusoidal clock is produced, and when OUTRefDiv = 1, a 20 MHz square clock is
produced (
The third overtone crystal requires external circuitry to load the crystal properly at the third-
overtone frequency while suppressing the fundamental frequency. This circuit is shown in
Figure
components should be RF type components (high Q) with good characteristics at 40 MHz.
