Crystals Procurement Notes

Verify the specific suffix 'CAT' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the target circuit's load capacitance requirements of 10pF. Confirm that the ±15ppm stability meets system timing constraints. Check for RoHS compliance status in the latest official documentation before finalizing procurement.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency is required in a compact SMD form factor. The 60 Ohm ESR must be compatible with the oscillator circuit design. Consider the ±15ppm tolerance relative to system jitter requirements. Verify that the 4-SMD footprint matches the PCB layout constraints and that the operating temperature range suits the deployment environment.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls. The series offers various frequencies in small surface-mount packages suitable for space-constrained electronics. The 402F540XXCAT specifically addresses the need for mid-range frequency generation in digital logic circuits requiring stable clock signals.

Crystals Replacement Considerations

Consult the manufacturer's cross-reference guide for direct substitutes. Ensure any replacement maintains the 54 MHz frequency, 10pF load capacitance, and 4-SMD package dimensions. Verify that alternative parts meet the same ±15ppm tolerance and ESR specifications.
