Crystals Procurement Notes

Verify the specific suffix requirements for your design, as the 'XX' indicates variable parameters that may differ from standard configurations. Confirm RoHS3 compliance status directly with the manufacturer or authorized distributors, as availability and exact specifications should be obtained from the official product data sheet prior to finalizing procurement plans.

Crystals Selection Notes

Select this component when a 54 MHz frequency with ±15ppm stability is required in a small 4-SMD footprint. Ensure the application circuit matches the 12pF load capacitance specification. Consider the 60 Ohm ESR value for oscillator circuit design compatibility. Verify that the -20°C to +70°C temperature range meets the operational environment requirements.
