Crystals Procurement Notes

Verify the specific operating temperature range required for your application, as available documentation presents conflicting specifications regarding the thermal limits of this component. Confirm that the 12pF load capacitance matches your circuit design requirements. Ensure the 4-SMD no-lead package footprint aligns with your PCB layout constraints before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 14.7456 MHz reference frequency is necessary for embedded applications. Consider the ECX-32 series form factor for space-constrained designs requiring surface-mount assembly. Evaluate the ±25ppm tolerance against your system's jitter sensitivity requirements. Verify compatibility with the intended load capacitance to ensure accurate frequency generation without external trimming.

Crystals Part Context

This part belongs to the ECX-32 series of crystals manufactured by ECS Inc. The series offers various frequency options in a compact surface-mount package. The model number indicates specific electrical characteristics including frequency, load capacitance, and tolerance. This component serves as a passive timing element rather than an active integrated circuit, despite some mislabeled descriptions found in third-party listings.

Crystals Replacement Considerations

The ECS-147.4-12-33-AGN-TR is a documented substitute variant within the same series. Both parts share identical electrical parameters including frequency, load capacitance, and package type. Differences may exist in packaging or specific manufacturing batches. Verify that any replacement maintains the 12pF load capacitance and 100 Ohm ESR values to ensure circuit compatibility.
