| - | See on kiibisisene taktigeneraator, mis ei vaja väliseid komponente, kuid pole ka kuigi kõrge sagedusega ega täpne. | + | This is a internal clock generator, which does not need any external components. Its main disadvantages are low frequency and inaccuracy. |

| - | ===== Kvartsostsillaator ===== | + | **Crystal Oscillator** |
| - | Kvartsostsillaatoris kasutatakse elektriväljas oma resonantssagedusel võnkuvat kristalli ja selle piesoelektrilist omadust mehhaanilisel deformatsioonil (võnkumisel) elektriväli tekitada. Kvartsostsillaatorit võimaldavad ligi 0,001% täpsust taktsagedust ja seda olenemata temperatuurist. | + | [{{ : |
| - | ===== Keraamiline resonaator ===== | + | Crystal oscillators use a crystal (usually quartz) that vibrates at its resonant frequency in the electric field and has a piezoelectic quality to produce an electric field during mechanical deformation (vibration). Crystal oscillators enable a precision of nearly 0.001%, which does not depend on the temperature. |
