• Utilizes a compact surface-mount 4-SMD package for efficient board space utilization
• Operates in base harmonic mode with specified electrical characteristics

Crystals Applications

• Precision timing circuits requiring stable clock signals
• Embedded systems utilizing 54 MHz reference frequencies
• Communication modules needing accurate frequency generation

Crystals Procurement Notes

Verify the specific suffix 'IJT' corresponds to the 9pF load capacitation requirement, as other suffixes like 'ILR' or 'IAR' indicate different capacitance values such as 12pF or 10pF. Confirm availability status as distribution channels may list discontinued or out-of-stock items. Ensure the selected variant matches the circuit design's capacitive load specifications to maintain frequency accuracy within the stated ±20ppm tolerance.

Crystals Selection Notes

Select this component when a 54 MHz crystal with 9pF load capacitance is required. Compare ESR values against oscillator drive levels to prevent over-driving. Consider the 4-SMD footprint compatibility with PCB layout constraints. Verify that the ±20ppm stability meets the system's timing requirements compared to lower-precision alternatives.

Crystals Part Context

This part belongs to the 402 Series of crystals from CTS-Frequency Controls. The series offers various frequency codes and package options. The 402F54022IJT specifically denotes the 54 MHz frequency code with the IJT suffix indicating the 9pF load capacitance configuration within this product line.

Crystals Replacement Considerations

Direct substitutes include 402F54022ILR and 402F54022IAR, though these feature different load capacitances (12pF and 10pF respectively). Verify circuit compatibility before swapping, as changing load capacitance affects frequency. Parameter-equivalent parts may exist but require validation of electrical specs.
