Crystals Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required load capacitance and frequency tolerance specifications. Confirm that the 4-SMD package dimensions align with the target PCB layout constraints. Check current availability status as supply levels may fluctuate due to manufacturing lead times.

Crystals Selection Notes

Select this component when a 30.72 MHz fundamental frequency with ±15ppm accuracy is required in a small form factor. Ensure the circuit design accounts for the 8pF load capacitance to maintain frequency accuracy. Compare ESR values against oscillator drive level requirements to prevent over-driving the crystal.
