2309NZ-1HDCGI

Overview

The Renesas 2309NZ-1HDCGI is a zero-delay buffer IC designed for high-speed clock distribution. It accepts one LVTTL input and provides nine LVTTL outputs with a 1:9 ratio, operating at frequencies up to 133 MHz. The device utilizes an internal PLL to align output phase with the input reference, eliminating propagation delay skew. It functions within a supply voltage range of 3V to 3.6V and is housed in a 16-SOIC package (0.154" width). The component supports commercial temperature operation from 0°C to 70°C.

Feature Summary

• Zero-delay buffering using internal PLL technology
• 1:9 input-to-output clock distribution ratio
• Maximum operating frequency of 133 MHz
• LVTTL input and output logic levels

Applications

• High-speed digital system clock distribution
• FPGA and ASIC clock tree generation
• Server and storage controller timing networks

Procurement Notes

Verify the specific suffix 'I' against official documentation to confirm industrial temperature rating (-40°C to 85°C) versus the standard commercial range (0°C to 70°C) listed in some distributor databases. Ensure the SOIC package dimensions match the design footprint requirements before procurement.

Selection Notes

Select this component when low-skew clock distribution is required for multiple loads from a single source. Confirm that the system operates within the 3V to 3.6V supply range and that LVTTL compatibility matches the connected devices. Verify if the industrial temperature grade is necessary for the application environment.

Part Context

This part belongs to the IDT 2309 series of zero-delay buffers, now manufactured by Renesas Electronics following the Integrated Device Technology acquisition. The 'NZ' designation typically indicates RoHS compliance and lead-free construction within this product family.

Replacement Considerations

Direct pin-compatible substitutes include other 1:9 zero-delay buffers from the same family, such as the 2309-1HDCG or 2309A-1 variants, provided temperature ranges and drive strengths are verified.
