Procurement Notes

Verify the specific voltage supply requirements and load conditions against the official datasheet before integration. Confirm that the 1.8V standby feature aligns with the target system's power architecture. Ensure the 4-SMD footprint matches the PCB design constraints. Cross-reference the latest revision status to guarantee component availability and long-term supply continuity.

Selection Notes

Select this component when a precise 50 MHz reference is required with low-power standby options. The CMOS output ensures direct interfacing with digital logic without additional buffering. The small form factor suits space-constrained designs. Evaluate thermal performance within the specified operating range to maintain frequency stability under varying environmental conditions.

Part Context

This part belongs to NDK's series of precision oscillators. It complements other models like the NSC5021A-25M and NSC5021A-45.1584M, offering different frequency options within the same package and functional family. These units are engineered for high reliability in consumer and industrial electronics requiring stable clock signals.

Replacement Considerations

Consult the official NDK substitution guide for verified alternatives. Direct replacements must match the 50 MHz frequency, CMOS output type, and 4-SMD package dimensions. Verify pin compatibility and electrical characteristics to ensure seamless integration into existing designs.
