Crystals Procurement Notes

Verify the specific suffix 'IDR' against official CTS documentation to confirm the exact load capacitance and tolerance specifications. Ensure the selected variant matches the required operating temperature range and package dimensions for the target PCB layout. Cross-reference the manufacturer datasheet for any recent design changes or obsolescence notices before finalizing procurement.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency with ±20ppm stability is required in a small SMD footprint. Consider the 18pF load capacitance requirement for oscillator circuit compatibility. Evaluate the -40°C to +85°C range against environmental conditions. Compare ESR values with other series options if drive level sensitivity is a critical design constraint.
