Crystals Procurement Notes

Verify the specific suffix 'CJR' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the ±30 ppm stability specification aligns with the target application's timing requirements. Ensure the 9 pF load capacitance matches the oscillator circuit design parameters to maintain accurate frequency performance within the specified temperature range.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 54 MHz applications with moderate stability needs. The 60 Ohm ESR value should be compatible with the driving circuit's power constraints. Consider the 4-SMD footprint dimensions for PCB layout compatibility. Verify that the -20°C to +70°C operating range satisfies the environmental conditions of the intended deployment scenario.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals, which are engineered for high reliability in consumer and industrial electronics. The series offers various frequency options and package sizes to support diverse design requirements. The 402F54033CJR specifically addresses the need for precise timing in space-constrained designs requiring fundamental mode operation.

Crystals Replacement Considerations

Direct substitutes include other 54 MHz crystals with identical 9 pF load capacitance, ±30 ppm stability, and 4-SMD no-lead footprint specifications. Verify equivalent ESR values and operating temperature ranges to ensure functional compatibility without circuit redesign.
