Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet STD-CSR-3 to ensure correct packaging and tolerance specifications. Confirm that the required load capacitance matches the target circuit design. Check for RoHS compliance status if restricted substances are a concern. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a 54.24 MHz fundamental frequency is required with tight ±10 ppm stability. The 10 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 60 Ohm ESR for drive level sensitivity and power consumption constraints. The 4-SMD package size fits space-constrained PCB layouts. Verify compatibility with the host MCU's oscillator input specifications before integration.

Part Context

This crystal belongs to NDK's general-purpose SMD crystal lineup, designed for mass production using synthetic quartz technology. It complements other frequencies in the same series, such as the CS14516-27.12M, offering consistent quality and reliability across different timing needs. The NX3225SA series designation indicates the package style and form factor common to many NDK surface-mount crystals.

Replacement Considerations

Direct substitutes include other 54.24 MHz crystals with identical 10 pF load capacitance and ±10 ppm tolerance in a 3.2x2.5mm 4-SMD package. Verify ESR compatibility, as differences in equivalent series resistance may affect start-up time and oscillation stability. Ensure the replacement part supports the same operating temperature range and mounting type.
