NB2309AI1DG

Overview

The NB2309AI1DG is a Zero Delay Buffer IC manufactured by onsemi, designed for clock distribution in high-speed digital systems. It features a single input and nine outputs with a maximum frequency of 133.33 MHz. The device operates within a supply voltage range of 3V to 3.6V and supports surface-mount installation in a 16-SOIC package (0.154 inch width). It functions without differential signaling or internal dividers/multipliers, ensuring minimal skew between the input and output clocks.

Feature Summary

• Zero Delay Buffer architecture for low-skew clock distribution
• 1:9 Input-to-Output ratio supporting up to 133.33 MHz
• Single circuit configuration with CMOS technology
• Operates at 3V to 3.6V supply voltage

Applications

• High-performance computing systems requiring precise clock synchronization
• Telecommunications infrastructure utilizing PLL-based clock drivers
• Industrial control systems needing reliable clock buffering

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as End-of-Life (EOL) with a notification date of March 29, 2022. Confirm RoHS compliance and material declarations via official manufacturer documentation before procurement. Check for alternative sourcing options due to limited availability.

Selection Notes

Select this component when a 1:9 clock fan-out with zero delay is required for 3.3V logic families. Ensure the design accommodates the 16-SOIC package dimensions and thermal requirements. Verify that the operating temperature range of -40°C to 85°C meets system environmental specifications.

Part Context

This part belongs to the NB2309A series of 3.3V Zero Delay Clock Buffers from onsemi. It shares functional similarities with other members like the NB2305A and NB2308A but differs in output count and package type. The AI1 suffix typically denotes specific commercial/industrial grade variations within the family.

Replacement Considerations

Publicly confirmed substitute part numbers include PL123-09SC and PL123-09SC-R from Microchip Technology. These are listed as similar replacements. Verify pinout compatibility and electrical parameters against original datasheets before substitution.
