Crystals Procurement Notes

Verify the specific package dimensions and pinout against the official manufacturer datasheet prior to PCB layout finalization. Confirm that the selected footprint matches the 4-SMD, No Lead form factor to ensure proper solder joint integrity during assembly processes. Cross-reference the electrical parameters with system requirements to validate compatibility with the target oscillator circuit design.

Crystals Selection Notes

Select this component when a precise 12.728125 MHz reference is required for digital systems. Ensure the application environment remains within the specified -20 to +70 ppm stability limits. Consider the 1 kΩ ESR value when designing the load capacitors and drive level constraints to maintain long-term frequency accuracy and prevent over-driving the crystal element.

Crystals Part Context

This part belongs to the standard crystal resonator category from CEC Xtal, focusing on fundamental frequency operation. It serves as a passive timing element distinct from active oscillators. The model designation indicates specific electrical characteristics including frequency, load capacitance, and tolerance levels defined by the manufacturer's coding system.

Crystals Replacement Considerations

Substitute only with components explicitly listed as direct replacements in official cross-reference documents. Verify identical frequency, load capacitance, tolerance, and package dimensions. Generic crystals with similar frequencies may not match the specific ESR or stability requirements.
