• PLCC-28 surface-mount package suitable for SMD/SMT installation

Clock Generators, PLLs, Frequency Synthesizers Applications

• Clock generation for wireless communication systems
• RF integrated circuit timing synchronization
• General-purpose programmable clock synthesis in industrial electronics

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify component status as the NBC12429FNR2G is listed as obsolete or end-of-life by the manufacturer. Confirm availability through secondary distributors or surplus suppliers. Check moisture sensitivity level (MSL) handling requirements prior to assembly. Validate RoHS compliance documentation. Ensure the specific PLCC-28 package matches design footprint constraints.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a fixed 1:1 ratio programmable PLL is required for frequencies up to 400 MHz. Compare against the NBC12430 series if higher output frequencies up to 800 MHz are needed. Consider the LQFP-32 package option (NBC12429AFAR2G) if different pinout compatibility is required. Verify that the 0°C to +70°C commercial temperature range meets application environmental specifications.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the NBC12429 family of programmable PLL clock generators. It shares core functionality with variants like the NBC12429AFAR2G, differing primarily in package type (PLCC-28 vs. LQFP-32) and potentially temperature range. The NBC12430 serves as a higher-frequency alternative within the same product line.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Evaluate the NBC12429AFAR2G for package-compatible alternatives or the NBC12430 series for performance upgrades. Consult manufacturer obsolescence notices for recommended next-step replacements.
