NB2779ASNR2

Overview

The NB2779ASNR2G is a clock synthesizer integrated circuit manufactured by onsemi, designed for frequency synthesis applications. It operates within a supply voltage range of 2.375V to 3.6V and supports a maximum frequency of 30MHz. The device is housed in a compact TSOT-23-6 (SOT-23-6 Thin) surface-mount package, suitable for space-constrained designs. It functions as a PLL-based clock generator without programmability features. The component is rated for an operating temperature range of 0°C to 70°C and complies with RoHS standards. This specific part number indicates the tape-and-reel packaging variant.

Feature Summary

• Integrated PLL clock synthesizer with a maximum output frequency of 30MHz
• Operates on a single supply voltage between 2.375V and 3.6V
• Compact TSOT-23-6 surface-mount package for efficient PCB layout
• Non-programmable fixed-frequency operation

Applications

• General clock generation for digital logic circuits
• Frequency synthesis in embedded systems
• Timing reference sources for low-speed peripherals

Procurement Notes

Verify the complete part number includes the suffix 'G', which denotes RoHS compliance. The base model NB2779ASNR2 may refer to the same family but requires confirmation of the specific suffix for accurate sourcing. Check manufacturer documentation for any obsolescence notices, as this component type may have limited availability or replacement recommendations from onsemi.

Selection Notes

Select this component when a fixed-frequency clock source up to 30MHz is required in a small footprint. Ensure the design voltage falls within the 2.375V to 3.6V range. Consider the TSOT-23-6 package constraints for thermal management and trace routing. Verify that non-programmable operation meets the system timing requirements without needing external configuration.

Part Context

This part belongs to the NB2779 series of clock synthesizers from onsemi. The 'A' typically indicates a specific bin or revision, while 'SNR2G' specifies the TSOT-23-6 package, tape-and-reel packaging, and RoHS compliance. It is distinct from other variants like the NB2779ASNR2GOSTR which may differ in packaging quantity or specific testing criteria.

Replacement Considerations

Consult onsemi official documentation for direct pin-to-pin replacements. The NB2779ASNR2GOSTR is a related variant with identical electrical characteristics but potentially different packaging quantities. No third-party substitutes are verified in public data.
