NB2309AI1HDTR2G

Overview

The NB2309AI1HDTR2G is a Zero Delay Buffer IC manufactured by onsemi, designed for clock distribution in high-speed digital systems. It features a single circuit with a 1:9 input-to-output ratio, supporting maximum frequencies up to 133.33 MHz. The device operates within a supply voltage range of 3V to 3.6V and is housed in a 16-TSSOP package (0.173", 4.40mm width). It supports surface mount installation and functions across an industrial temperature range of -40°C to +85°C. The component includes a Phase-Locked Loop (PLL) with bypass capability.

Feature Summary

• Zero Delay Buffer architecture ensuring minimal skew between input and output clocks
• 1:9 Input/Output ratio for distributing a single clock signal to nine destinations
• Maximum operating frequency of 133.33 MHz
• Integrated PLL with bypass functionality

Applications

• High-speed data acquisition systems requiring precise clock synchronization
• Digital signal processing (DSP) architectures
• Communication equipment clock distribution networks

Procurement Notes

Verify the specific suffix 'HDTR2G' against official onsemi documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and REACH registration details prior to procurement. Check for Product Change Notifications (PCN) or End-of-Life (EOL) notices, as availability may be limited compared to standard variants.

Selection Notes

Select this component when a 1:9 fan-out buffer is required with zero-delay characteristics. Ensure the design accommodates the 3V to 3.6V supply voltage range. Verify that the 16-TSSOP package dimensions fit the PCB layout constraints. Compare against similar models like NB2308A if fewer outputs are sufficient.

Part Context

This part belongs to the NB2309A family of 3.3V Zero Delay Clock Buffers from onsemi. It shares functional similarities with other members of the NB230x series but is distinguished by its 1:9 output configuration. The device is intended for applications requiring low-jitter clock distribution without introducing propagation delay relative to the input source.
