NB2879ASNR2G

Overview

The NB2879ASNR2G is a clock synthesizer integrated circuit manufactured by onsemi, designed for frequency synthesis applications. It operates within a supply voltage range of 3V to 3.6V and supports a maximum frequency of 30MHz. The device features a single circuit configuration with a 1:2 input-to-output ratio, utilizing CMOS inputs and outputs. It accepts CMOS or crystal inputs and provides differential input/output capabilities as none. The component is housed in a compact SOT-23-6 thin package (TSOT-23-6) and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates a phase-locked loop (PLL) for precise clock frequency synthesis
• Supports both CMOS logic and crystal oscillator inputs
• Delivers dual CMOS outputs from a single input source
• Operates reliably across standard commercial temperature ranges

Applications

• General-purpose clock generation for digital systems
• Frequency synthesis in embedded electronics
• Timing reference distribution in consumer devices
• Clock signal conditioning for microcontroller interfaces

Procurement Notes

Verify the specific suffix 'ASNR2G' against official onsemi documentation to confirm pinout compatibility and electrical specifications. Confirm that the TSOT-23-6 package dimensions match your PCB footprint requirements. Check current availability status as this component may be subject to lifecycle changes. Ensure that the 3V to 3.6V supply voltage aligns with your system design constraints before finalizing procurement.

Selection Notes

Select this component when a compact solution for generating two synchronized clock signals from a single source is required. It is suitable for designs needing a 1:2 frequency division or multiplication within the 30MHz limit. Consider the SOT-23-6 package size if space constraints are critical. Verify that the CMOS output drive strength meets the load requirements of the downstream components in the application circuit.

Part Context

This part belongs to the NB2879 series of clock synthesizers from onsemi. It shares functional similarities with other members like the NB2872ASNR2G but offers specific input/output configurations tailored for certain timing needs. The series is designed for low-cost, high-performance clock generation in portable and industrial applications requiring reliable frequency synthesis.

Replacement Considerations

Direct substitutes include NB2879ASNR2GOSTR and NB2879ASNR2GOSCT, which share identical electrical characteristics and pinouts. Cross-reference with NB2872ASNR2G only if the specific input/output ratio differences are acceptable for the design.
