NB2879ASNR2

Overview

The NB2879ASNR2 is a low-power clock synthesizer integrated circuit manufactured by onsemi. 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 TSOT-23-6 package, also referred to as SOT-23-6 Thin, and is designed for surface-mount installation. It functions as a clock generator utilizing CMOS technology and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Low power consumption with a typical current draw of 4mA
• Integrated clock synthesis functionality for precise frequency generation
• Designed to reduce electromagnetic interference (EMI) in digital systems

Applications

• Clock distribution in consumer electronics
• Frequency synthesis for embedded systems
• Digital signal processing applications requiring stable timing references

Procurement Notes

Verify the specific ordering suffix and manufacturer designation carefully, as this component has been associated with multiple entities including AMI Semiconductor and onsemi. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary due to its discontinued or legacy status. Ensure the package type matches the required PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when a low-power, fixed-frequency clock source is required for 3.3V logic systems. Consider the TSOT-23-6 package size constraints and the 30MHz maximum frequency limit. Evaluate thermal requirements against the 0°C to 70°C operating range. Compare against newer onsemi clock synthesizers if extended temperature ranges or higher frequencies are necessary for the target application.

Part Context

This part belongs to the NB2779/NB2879 family of clock synthesizers from onsemi. These devices are typically used to generate clean clock signals for high-speed digital circuits. The NB2879 variant specifically offers low power operation and EMI reduction features, making it suitable for space-constrained and noise-sensitive applications within the broader portfolio of timing solutions offered by the manufacturer.

Replacement Considerations

The NB2779ASNR2G is listed as a related product in official catalogs. Verify electrical compatibility and pinout alignment before substitution. Check for updated datasheets regarding performance characteristics and packaging variations.
