Applications
Crystal Unit design checklist
Review the component with its oscillator circuit and include these conditions in your inquiry.
- Frequency and temperature
- List nominal frequency, tolerance and operating temperature, and review datasheet test conditions.
- Load and drive
- Provide the IC, target load capacitance and ESR/drive requirements and review the IC design documentation.
- Layout and samples
- Review dimensions, landing patterns and layout; record board revision, method and environment during sample tests.
