Detailed Specifications
Quartz Crystal Oscillator
In wireless systems, a quartz-controlled oscillator ensures that transmitters and receivers work at exact frequencies, keeping them "in tune" with one another. Many radios, smartphones, and other wireless communication devices use quartz crystals to generate these fixed frequencies for modulation and demodulation of signals.
Advantages:
- High stability and precision: Quartz oscillators are known for being extremely accurate and resistant to environmental changes like temperature shifts.
- Low drift: Over time, the frequency remains almost constant, which is essential for reliable wireless communication.
