Crystals Procurement Notes

Verify the specific load capacitance requirement against circuit design specifications before procurement. Confirm that the 60 Ohm ESR aligns with the oscillator circuit's drive level constraints. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the package dimensions with the PCB footprint to guarantee mechanical compatibility during assembly.

Crystals Selection Notes

Select this component when a 38.4 MHz frequency is required with a ±15ppm stability margin. Consider the 12pF load capacitance for matching oscillator circuit parameters. Evaluate the 4-SMD package size for space-constrained layouts. Assess the -20°C to +70°C temperature range against operational environments. Compare ESR values with alternative crystals to ensure proper start-up characteristics.

Crystals Part Context

This part belongs to the 402 series of MHz crystals from CTS-Frequency Controls. The series offers various frequency options and package configurations. The 402F384XXCLR specifically targets applications needing a 38.4 MHz reference. It shares common design principles with other parts in the 402 family regarding surface mount technology and reliability standards.

Crystals Replacement Considerations

The 402F384XXCAR is a similar variant within the same product line. Both share the 38.4 MHz frequency and ±15ppm tolerance. Differences exist in load capacitance and ESR values between these two part numbers. Verify electrical parameter compatibility before substituting one for the other.
