Crystals Procurement Notes

Verify the specific suffix 'I' against official CTS documentation to confirm intended application grade or environmental rating differences compared to standard variants. Ensure the required load capacitance matches the target circuit design. Confirm that the 60 Ohm ESR limit aligns with the oscillator circuit requirements. Validate that the 100 uW drive level specification prevents over-driving the crystal in the final application.

Crystals Selection Notes

Select this component when a fundamental mode crystal at 14.31818 MHz is required with tight initial tolerance. The 13 pF load capacitance must match the external capacitors in the oscillator circuit to achieve accurate frequency. Consider the 60 Ohm ESR limit when designing the oscillator loop gain. The 4-SMD footprint requires appropriate PCB land pattern design for reliable soldering. Verify compatibility with the operating temperature range of the end product.
