Crystals Procurement Notes

Verify the specific manufacturer designation when sourcing, as distributors may list this part under various identifiers. Confirm that the received component matches the 12.88643 specification sheet regarding frequency and package type. Ensure compliance with RoHS standards if required by your manufacturing process. Cross-reference ordering codes carefully to avoid substitutions that may differ in electrical characteristics or physical dimensions.

Crystals Selection Notes

Select this component when a 14.31818 MHz reference signal is required in a 4-SMD package. The 12 pF load capacitance must align with the oscillator circuit design. Consider the ±50 ppm stability tolerance against system timing requirements. The 70 Ohm ESR value should be compatible with the driving circuit's impedance matching needs for reliable oscillation startup.
