Crystals, Oscillators, Resonators
Crystal, oscillator, and resonator products are critical components used for generating and measuring frequency and time. These devices typically utilize the physical vibration of a mechanical structure at a known frequency to provide a stable and precise signal. They can be further classified based on their specific design and the level of additional functionality incorporated into them to facilitate ease of use or improve precision and accuracy.
Crystals: Crystals are passive components that provide a high degree of frequency stability and accuracy. They are commonly used in digital circuits and communications systems.
Oscillators: Oscillators are active components that generate a periodic signal at a specific frequency. They come in various types, including quartz, surface acoustic wave (SAW), and temperature-compensated (TCXO) oscillators.
Resonators: Resonators are passive components that provide a stable frequency reference by utilizing the resonance properties of a mechanical structure. They are commonly used in timing applications and electronic filters.
Voltage-Controlled Oscillators (VCOs): VCOs are oscillators whose output frequency can be adjusted by varying an applied voltage. They are widely used in frequency synthesis and modulation applications.
Oven-Controlled Crystal Oscillators (OCXOs): OCXOs are highly stable and accurate oscillators that offer superior temperature stability by incorporating a temperature-controlled oven.
Crystal Oscillators with Phase-Locked Loop (PLL): These oscillators combine the stability of a crystal with the frequency multiplication capabilities of a PLL, resulting in a highly precise and stable signal.
Programmable Oscillators: Programmable oscillators offer a high degree of flexibility by allowing users to adjust the output frequency through software control.
Crystal Filters: Crystal filters are electronic circuits that use crystals to filter out unwanted frequencies from a signal. They are commonly used in radio communications and audio applications.
Surface Acoustic Wave (SAW) Filters: SAW filters are electronic circuits that employ a piezoelectric crystal to filter out unwanted frequencies. They offer high selectivity and low insertion loss.
These products offer a wide range of frequency generation and measurement capabilities, catering to diverse applications across various industries. Their stable and accurate signals are essential for ensuring reliable operation and optimal performance of electronic systems.
