Crystals Procurement Notes

Verify the specific package variant against the official datasheet to ensure compatibility with PCB footprint requirements. Confirm that the 50 Ohm ESR aligns with the oscillator circuit design parameters. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the ±20ppm stability meets the system timing accuracy requirements before procurement.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with moderate stability. The 8pF load capacitance must match the external capacitors in the oscillator circuit to achieve accurate frequency output. Consider the 4-SMD package size for space-constrained designs. Verify temperature range suitability for the intended operating environment.

Crystals Part Context
