Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure compatibility with required load capacitance and tolerance levels. Confirm that the operating temperature range meets the environmental requirements of the target application. Cross-reference the package dimensions with the PCB footprint design to guarantee proper solder joint formation and mechanical reliability during reflow processes.

Crystals Selection Notes

Select this component when a 16.384 MHz reference with tight ±10 ppm accuracy is required. Ensure the circuit design accounts for the 10 pF load capacitance specification to maintain frequency accuracy. Verify that the 60 Ohm ESR value is compatible with the oscillator circuit's drive level constraints to prevent overdriving the crystal element.
