NB2309AI1DTR2G

Overview

The NB2309AI1DTR2G is a Zero Delay Buffer IC manufactured by onsemi, designed for clock distribution applications. It features a 1:9 input-to-output ratio and supports maximum frequencies up to 133.33MHz. The device operates within a supply voltage range of 3V to 3.6V and functions across an industrial temperature range of -40°C to +85°C. Packaged in a 16-SOIC surface-mount format with a width of 3.90mm, it provides single-circuit clock buffering without differential signaling or frequency multiplication capabilities.

Feature Summary

• Zero Delay Buffer architecture ensuring minimal clock skew
• 1:9 Input to Output ratio for multi-point clock distribution
• Maximum operating frequency of 133.33MHz
• Single-ended clock input and output configuration

Applications

• High-speed digital system clock distribution
• FPGA and ASIC clock tree generation
• Telecommunications equipment timing networks

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS3 compliance and MSL Level 1 handling requirements during storage and assembly. Check for valid PCN documentation regarding manufacturing changes prior to procurement integration.

Selection Notes

Select this model when nine buffered clock outputs are required from a single source. Ensure the design accommodates the 16-SOIC package dimensions and 3V-3.6V power supply constraints. Verify that single-ended inputs meet the system's signal integrity requirements compared to differential alternatives.

Part Context

This component belongs to the NB2309 family of zero-delay buffers. It shares functional similarities with other onsemi clock buffer series but is distinguished by its specific 16-pin SOIC packaging and 1:9 fan-out capability. It serves as a specialized solution for distributing reference clocks to multiple synchronous components.

Replacement Considerations

Publicly confirmed substitute part numbers include PL123-09SC and PL123-09SC-R from Microchip Technology. These are listed as similar replacements.
