A crystal is a passive component that requires an external circuit to oscillate. An oscillator is an active device that includes the crystal and the drive circuitry in a single package.
Crystals, Oscillators, and Resonators Component Intelligence
Engineering precision timing and frequency control for stable system performance.
What are Crystals, Oscillators, and Resonators components?
Frequency control components provide the heartbeat for digital systems. Choose based on required stability (ppm), jitter, phase noise, and power budget. Crystals require external load circuitry, while oscillators provide integrated, ready-to-use clock solutions.
How to Choose Crystals, Oscillators, and Resonators Components
Selecting the right timing reference requires balancing stability, cost, and integration complexity.
Stability vs. Cost
Determine if your application requires the high stability of an OCXO or if a standard XO or crystal suffices.
Load Capacitance
For passive crystals, ensure the load capacitance matches your IC's oscillator circuit to prevent frequency drift.
Jitter and Phase Noise
Critical for high-speed data links; prioritize low-jitter oscillators to maintain signal integrity.
Environmental Factors
Consider temperature range and vibration resistance, especially for industrial or automotive designs.
Integration Level
Choose between raw crystals (lower cost, higher design effort) or oscillators (higher cost, plug-and-play).
