Crystals Procurement Notes

Verify the specific suffix (IDR) against the manufacturer's current datasheet to confirm lead time and availability status. Ensure the ordering quantity meets minimum requirements. Cross-reference the pinout and loading capacitance specifications with the target circuit design to guarantee compatibility before finalizing procurement.

Crystals Selection Notes

Select this component when a 54 MHz reference is required in a small form factor. Consider the ±10 ppm tolerance and 18 pF load capacitance requirements of the host oscillator circuit. Evaluate the 60 Ohm impedance against the drive level constraints of the application to prevent frequency pulling or damage.
