NB2304AI1DR2G

Overview

The NB2304AI1DR2G is a zero-delay buffer integrated circuit manufactured by onsemi. It operates as a Phase Locked Loop (PLL) based clock driver designed for 3.3 V applications. The device features a single input and four outputs, providing a 1:4 input-to-output ratio. It supports maximum frequencies up to 133.3 MHz. The component is housed in an 8-SOIC package with a width of 3.90 mm. It functions within a supply voltage range of 3 V to 3.6 V and is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Zero-delay buffer architecture utilizing PLL technology
• Four output channels with 1:4 input-to-output ratio
• Maximum operating frequency of 133.3 MHz
• Industrial temperature range from -40°C to +85°C

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 DR2G against official datasheets to confirm packaging type and reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or onsemi, as availability varies by region and production lot. Ensure the source document explicitly lists this exact part number to avoid confusion with similar variants like NB2304AC1DR2G.

Selection Notes

Select this component when a low-skew, zero-delay buffering solution is required for 3.3 V logic families. The 1:4 fan-out capability makes it suitable for driving multiple loads from a single source. Verify that the system power supply remains within the 3 V to 3.6 V range and that the operating environment stays within the specified industrial temperature limits.

Part Context

This part belongs to the NB2304A family of zero-delay buffers from onsemi. Other members include NB2304AC1DR2G and NB2304AI1HDG. These devices share similar core PLL functionality but differ in package types, temperature grades, and output configurations. The AI1DR2G variant specifically denotes the industrial grade and SOIC-8 tape-and-reel packaging.

Replacement Considerations

Direct substitutes may include other NB2304A family members if pin compatibility and electrical parameters match. Cross-vendor alternatives such as Cypress CY2305C offer similar zero-delay buffering functions but require verification of pinout and voltage levels.
