Crystals Procurement Notes

Verify the specific suffix 'I' indicates the required temperature range and packaging configuration against official datasheets. Confirm that the 13pF load capacitance matches the target oscillator circuit requirements. Ensure the 60 Ohm ESR value is compatible with the driving circuit's power constraints to prevent over-driving the crystal.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency is required in a compact 5.0x3.2mm footprint. Consider the ±30 ppm tolerance if higher precision is needed, or evaluate alternative packages if board space allows for different form factors. Verify compatibility with the host system's operating temperature limits before finalizing the design.
