NB2669ASNR2G

Overview

The NB2669ASNR2G is a clock/frequency synthesizer integrated circuit manufactured by onsemi. It operates with a maximum frequency of 13MHz and utilizes an internal Phase-Locked Loop (PLL) for signal generation. The device accepts CMOS input signals and provides a single CMOS output, maintaining a 1:1 input-to-output ratio without differential signaling capabilities. It functions within a supply voltage range of 2.375V to 3.6V and supports an operating temperature range of 0°C to 70°C. The component is housed in a compact SOT-23-6 Thin or TSOT-23-6 surface-mount package.

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Availability is limited to secondary market distributors such as Rochester Electronics, LLC. Verification of part authenticity and condition is critical when sourcing from non-primary channels due to the discontinued status.

Selection Notes

Select this component only if a fixed 13MHz CMOS clock output is required within a 2.375V–3.6V supply range. Ensure the design accommodates the SOT-23-6 Thin footprint. Note that the device lacks programmability features and differential outputs; alternative models may be necessary for variable frequencies or higher performance requirements.

Part Context

The NB2669ASNR2G belongs to the NB2669 family of clock synthesizers. It serves as a specialized solution for generating stable clock signals in space-constrained applications using the TSOT-23-6 package. The 'SNR2G' suffix indicates specific packaging and environmental compliance attributes defined by onsemi.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements must be verified through current onsemi product portfolios or authorized distributor cross-reference tools.
