• Digital signal processing systems

Crystals Procurement Notes

Verify the specific suffix 'ILR' against official CTS documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with standard SMD reflow profiles. Cross-reference the exact part number with current manufacturer availability lists, as electronic components may undergo lifecycle changes or obsolescence notices without immediate public announcement.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency with 12 pF load capacitance is required. The 80 Ohm ESR value must match the oscillator circuit design constraints. Consider the ±20 ppm stability requirement against system jitter budgets. Verify that the 4-SMD package dimensions fit the PCB layout constraints and thermal management requirements for the target application environment.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It is functionally similar to other variants in the series but distinguished by its specific 12 pF load capacitance and ILR packaging suffix. It serves as a timing reference in digital electronics where moderate stability and low cost are prioritized over high-precision performance found in TCXO or OCXO solutions.

Crystals Replacement Considerations

Direct substitutes include the 402F30022IAR, which shares the same frequency and package but utilizes a 10 pF load capacitance instead of 12 pF. Circuit redesign may be necessary if the load capacitance difference impacts oscillator startup or stability. Always verify electrical parameters against the original design requirements before substitution.
