NB2309AI1HDR2G

Overview

The NB2309AI1HDR2G is a zero-delay clock buffer manufactured by onsemi, belonging to the NB2309A series. It operates within a supply voltage range of 3 V to 3.6 V and supports input frequencies from 15 MHz to 133 MHz. The device features a single circuit with CMOS input and output interfaces. It is housed in an 8-SOIC package (0.154", 3.90mm width) designed for surface-mount installation. The component functions as a PLL-based clock buffer intended for precise timing applications.

Feature Summary

• Zero-delay PLL architecture for minimal clock skew
• Supports frequency range of 15 MHz to 133 MHz
• CMOS input/output compatibility
• Operates on 3.3 V nominal supply (3 V to 3.6 V)

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via current datasheets. Check for End-of-Life (EOL) notifications or Production Change Notices (PCN) prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the package documentation.

Selection Notes

Select this component when a single-input, multi-output zero-delay buffer is required for 3.3 V logic systems. Verify that the 8-SOIC package dimensions fit the PCB layout constraints. Ensure the operating temperature range of -40°C to +85°C matches the environmental specifications of the target application.

Part Context

This part belongs to the NB2309A family of 3.3 V zero-delay clock buffers. It shares functional similarities with other members like the NB2304A and NB2305A but differs in pinout and specific output configurations. The 'HDR' suffix typically indicates tape-and-reel packaging for automated assembly.

Replacement Considerations

Direct substitutes include NB2309AI1HDG (tube packaging) or NB2309AI1DTR2G (TSSOP-8 package). Cross-vendor equivalents such as Cypress CY2309 may require schematic and firmware adjustments due to pinout differences.
