NB2304AI1DG

Overview

The NB2304AI1DG is a 3.3 V zero delay clock buffer manufactured by onsemi, belonging to the NB2304A series. It functions as a Phase Locked Loop (PLL) based clock driver with one circuit and four outputs. The device supports an output frequency range of 15 MHz to 133 MHz and operates within a supply voltage window of 3 V to 3.6 V. Designed for surface mount installation, it utilizes an 8-SOIC package. The component is rated for industrial temperature operation from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Zero Delay Buffer architecture providing 1:4 input-to-output ratio
• Integrated PLL for clock signal buffering and distribution
• Operates at 3.3 V nominal supply voltage (3 V to 3.6 V range)
• Supports output frequencies up to 133 MHz

Applications

• Clock distribution in high-speed digital systems
• Buffering reference clocks for data converters
• Timing synchronization in communication equipment

Procurement Notes

Verify the specific suffix 'DG' against official onsemi documentation to confirm package type and tape/reel specifications. Confirm current lifecycle status, as similar variants in this series may be subject to End-of-Life notices or production suspensions. Ensure compatibility with required moisture sensitivity levels and soldering profiles during procurement planning.

Selection Notes

Select this component when a single-ended CMOS input requires buffering into four synchronized single-ended CMOS outputs with minimal propagation delay skew. Verify that the required operating temperature range includes -40°C to +85°C and that the 8-SOIC footprint fits the design constraints. Compare against other members of the NB2304A family if different output counts or packaging options are needed.

Part Context

This part belongs to the NB2304A family of 3.3 V zero delay buffers. Related components include the NB2305A (five outputs), NB2308A, and NB2309A. These devices share similar electrical characteristics and PLL-based architectures but differ in output count and pin configurations. The NB2304A series is designed for low-power, high-performance clock distribution applications.

Replacement Considerations

Publicly confirmed substitute part numbers for NB2304AI1DG were not identified in the provided source material. Cross-reference with other NB2304A variants or competitor devices such as the Cypress CY2305C only after verifying pinout and electrical parameter compatibility through official datasheets.
