2305NZ-1HDCG

Overview

The Renesas 2305NZ-1HDCG is a high-speed clock buffer designed for distributing reference clocks in digital systems. It accepts one input and drives five low-skew outputs, operating within a supply voltage range of 2.3 V to 2.7 V. The device features a maximum propagation delay of 8.7 ns and functions within a commercial temperature range of 0°C to +70°C. Packaged in an 8-pin SOIC format, it utilizes surface-mount technology for integration into compact circuit designs requiring precise timing distribution.

Feature Summary

• Five output channels providing low-skew clock distribution
• Operates on a 2.5 V power supply with a range of 2.3 V to 2.7 V
• Maximum propagation delay of 8.7 ns
• Commercial temperature rating from 0°C to +70°C

Applications

• SDRAM clock distribution
• Telecommunications equipment
• Datacom signal processing
• PC motherboards and workstations

Procurement Notes

Verify the specific suffix 'NZ' against official Renesas documentation to confirm the exact voltage and temperature specifications, as standard 2305 variants often differ. Ensure the package type matches the required PCB footprint. Confirm RoHS compliance status through the manufacturer's current environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V supply is available and zero-delay PLL functionality is not required. Compare the 8.7 ns propagation delay against system timing budgets. Verify that the 5-output configuration meets the design requirements without needing additional buffering stages or higher drive strength versions.

Part Context

This part belongs to the 2305NZT series of clock buffers. It serves as a non-zero delay alternative to the PLL-based 2305 family, offering simpler implementation for applications where phase alignment is less critical than raw speed and low skew. It complements the broader Renesas clocking portfolio by addressing specific voltage and form-factor needs.

Replacement Considerations

The IDT2305NZT-1DCG is listed as an alias for this component. Verify pinout compatibility if substituting with other 2305-series parts, as drive strength and voltage tolerances may vary between different suffixes.
