2309NZ-1HDCG

Overview

The Renesas 2309NZ-1HDCG is a zero-delay clock 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, achieving low skew characteristics. It operates within a supply voltage range of 3V to 3.6V and is housed in a 16-SOIC package (0.154 inch width). The component supports commercial temperature operation from 0°C to +70°C.

Feature Summary

• Zero-delay buffer architecture using on-chip PLL for phase alignment
• 1:9 input-to-output ratio distributing one clock to nine outputs
• Maximum operating frequency of 133 MHz with LVTTL I/O levels
• Low skew performance suitable for high-speed digital systems

Applications

• High-speed clock distribution networks
• System-on-Chip (SoC) clock generation
• FPGA and ASIC clock buffering
• Telecommunications equipment timing circuits

Procurement Notes

Verify the specific suffix 'NZ' against official Renesas documentation to confirm industrial-grade temperature rating or RoHS compliance status, as distributor listings may vary. Confirm the 16-SOIC package dimensions match design constraints. Check for moisture sensitivity level requirements during assembly processing.

Selection Notes

Select this component when a single reference clock must drive multiple synchronous loads with minimal skew. Ensure the system requires LVTTL logic levels and operates within the 3V to 3.6V supply range. Verify that the 133 MHz maximum frequency meets the target application's speed requirements compared to lower-frequency alternatives in the 2309 family.

Part Context

This part belongs to the Renesas 2309 series of zero-delay buffers, originally developed by Integrated Circuit Systems (ICS). The 'NZ' designation typically indicates specific environmental or compliance variations within the product line. The 'H' suffix denotes high-drive capability for faster rise and fall times compared to standard drive versions.

Replacement Considerations

The IDT2309-1HDCG is a direct functional equivalent within the same product lineage. Other variants such as the 2309-1HDCG offer similar electrical characteristics but may differ in temperature range or packaging specifications.
