Crystals Procurement Notes

Verify the specific suffix 'IJR' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Check for active status or obsolescence notices directly from CTS-Frequency Controls. Ensure compatibility with existing board footprints and reflow soldering profiles specified in the official documentation before integration.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with 9 pF load capacitance is required. The 60 Ohm ESR value must match the oscillator circuit design constraints. Consider the ±20 ppm stability requirement relative to system timing accuracy needs. Verify that the 4-SMD package dimensions fit within the available area on the target printed circuit board.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequencies and packages optimized for surface mount technology. The 402F54022IJR specifically addresses applications requiring precise 54 MHz timing in a small form factor. Other variants in the series differ in frequency, capacitance, and physical dimensions.

Crystals Replacement Considerations

Direct substitutes include parts with identical 54 MHz frequency, 9 pF load capacitance, and 60 Ohm ESR in the same 4-SMD package. Verify parameter equivalence for frequency stability and temperature range. Cross-reference with other manufacturers offering RoHS-compliant SMD crystals meeting these exact electrical and mechanical specifications.
