Crystals Procurement Notes

Verify the specific suffix requirements against the official CTS datasheet to ensure compatibility with your circuit's load capacitance and stability needs. Confirm that the 4-SMD footprint matches your PCB layout constraints. Check for any recent obsolescence notices or alternative package options if supply chain continuity is a concern for long-term production.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±15 ppm tolerance is required for space-constrained designs. The 100 Ohm ESR value should be compatible with the driving circuit's oscillation requirements. Ensure the 10 pF load capacitance aligns with the system's total stray capacitance to maintain accurate frequency performance.
