Crystal resonators use quartz crystals to generate precise clock signals and are used in devices like communication systems, automotive electronics, and appliances. Key types include: Clock Crystal Oscillators (for timekeeping), Voltage-Controlled Oscillators (VCXO, for fine frequency tuning), Temperature-Compensated Oscillators (TCXO, for stable performance in varying temperatures), Oven-Controlled Oscillators (OCXO, for high-frequency stability), and SAW Resonators (for high-frequency applications). Each type is designed for specific needs like stability, size, and frequency control.
