NB2305AI1D

Overview

The NB2305AI1D is a 3.3 V zero delay clock buffer manufactured by onsemi, designed to distribute high-speed clocks with low skew. It accepts one reference input and drives five buffered outputs using an internal PLL locked to the REF pin. The device operates within a frequency range of 15 MHz to 133 MHz and supports CMOS inputs and outputs. It is available in an 8-pin SOIC package (D suffix) and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Zero Input-Output Propagation Delay
• Output-to-Output Skew Less than 250 ps
• Device-to-Device Skew Less than 700 ps
• Less than 200 ps Cycle-to-Cycle Jitter

Applications

• CPU Clock Distribution
• PCI Bus Frequency Distribution
• Pentium/C0082 Based Systems

Procurement Notes

Verify component authenticity through authorized channels. Confirm that the ordering suffix 'D' corresponds to the SOIC-8 package as specified in the datasheet. Ensure compatibility with industrial temperature requirements (-40°C to +85°C). Check for Pb-Free status if required by environmental regulations.

Selection Notes

Select the NB2305AI1D for applications requiring precise clock distribution with minimal skew. The 'I' suffix indicates industrial temperature rating suitable for harsh environments. The '1' designation specifies the standard drive version; choose 'H' variants only if higher drive strength and faster rise/fall times are necessary.

Part Context

This component belongs to the NB2305A family of 3.3 V zero delay buffers. It shares functional similarities with other members like NB2304A and NB2308A but differs in output count and specific electrical characteristics. The NB2305A utilizes advanced 0.35 µm CMOS technology for efficient power consumption and performance.

Replacement Considerations

Direct replacements include NB2305AC1D for commercial temperature ranges or NB2305AI1DG for Pb-free versions. For higher drive capabilities, consider NB2305AI1HD. Verify package compatibility and electrical parameters before substitution.
