Applications

• General purpose clock signal generation in electronic circuits
• Timing reference for microcontroller systems
• Frequency control in consumer electronics devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet STD-CSR-1 to ensure correct packaging and tolerance specifications. Confirm that the required load capacitance matches the system design requirements before finalizing procurement orders.

Selection Notes

Select this component when a 48 MHz fundamental resonance is required in a compact SMD form factor. Ensure the application environment remains within the specified -10°C to +75°C operating temperature range. Verify that the system circuit can accommodate the 50 Ohm ESR characteristic for proper oscillation startup.

Part Context

This part belongs to the NX3225SA series of surface mount crystals from NDK. It provides a standard 48 MHz frequency solution suitable for general timing applications. The component is distinct from oscillator variants as it requires an external oscillator circuit for operation.

Replacement Considerations

Cross-reference with other 48 MHz 4-SMD crystals having identical 3.2x2.5mm dimensions and 8pF load capacitance. Verify pin compatibility and electrical parameters such as ESR and stability before substituting.
