quartz oscillator
Noun: A quartz oscillator is an electronic oscillator circuit that generates a precise and stable electrical signal. Its frequency is determined by the mechanical resonance of a vibrating quartz crystal. The crystal acts as a piezoelectric resonator, converting electrical energy into mechanical vibrations and vice versa, creating a highly accurate frequency reference.
The term quartz oscillator is used to describe the core timing component in many electronic devices. It is a technical noun, typically used in engineering, electronics, and physics contexts.
- The stability of a digital clock depends on its quartz oscillator.
- Modern communication systems rely on the precise frequency generated by a quartz oscillator.
- Replacing the faulty quartz oscillator fixed the microcontroller's timing issues.
- As a compound noun modifier: The term is often used attributively to specify the type of component or technology.
- quartz oscillator circuit, quartz oscillator design, quartz oscillator stability
- Crystal Oscillator: A more general synonym. While all quartz oscillators are crystal oscillators (using a quartz crystal), not all crystal oscillators use quartz (some may use other piezoelectric materials like ceramic).
- Quartz Crystal: Refers specifically to the piezoelectric resonator itself, which is the key element within the quartz oscillator.
- XO (Crystal Oscillator): A common abbreviation in electronics.
- TCXO (Temperature-Compensated Crystal Oscillator) and OCXO (Oven-Controlled Crystal Oscillator): More advanced, stable types of quartz oscillators with additional circuitry to minimize frequency drift caused by temperature changes.
- Crystal Oscillator
- Piezoelectric Oscillator (less common, more technical)
The definition is highly specific to electronics. There are no separate idiomatic meanings or phrasal verbs associated with this technical compound noun. Its meaning is consistent across contexts, always referring to the electronic timing device.
-
an oscillator that produces electrical oscillations at a frequency determined by the physical characteristics of a piezoelectric quartz crystal
