12 MHz Crystal Oscillator - (Pack of 10) Original Arduino MQ136 gas sensor has a12 MHz Crystal Oscillator (Pack of 10) The 12MHz crystal oscillator circuit sustains oscillation by taking a voltage signal from the quartz resonator, amplifying it, and feeding it back to the resonator. It provides clock pulses of 12MHz frequency. The popularity of the crystals is due to the low cost. How are 12MHz crystal oscillators useful? One of the most important traits of the crystal oscillator is that it exhibits very low phase noise. In the
