Using such a circuit can produce very stable frequencies and since the 32.768 kHz crystal is a power of 2, you get nice divisions out of the counter. We’ve seen the same trick done with decade ...

065TSMC_OSC_02 is a CMOS inverter of a pierce-type variation with an integrated Crystal (Xtal) oscillator that is optimized in parallel mode for very high accuracy and very low power consumption.

To test this, [SDG Electronics] built a board with various potentially vulnerable components, including the popular 32.768-kHz crystal, cut for a frequency quite close to the cleaner’s fundamental.
