2305NZ-1HDCG8

Overview

The Renesas Electronics Corporation 2305NZ-1HDCG8 is a high-speed clock buffer designed for demanding clock distribution applications. It accepts one reference input and drives five low-skew clock outputs, operating at frequencies up to 133.33 MHz. The device utilizes a Phase-Locked Loop (PLL) architecture to achieve zero delay between the input and output clocks. It operates on a single 3V to 3.6V power supply and is housed in an 8-pin SOIC package with a width of 3.90mm. The component supports LVCMOS/LVTTL input types and provides CMOS/LVCMOS/TTL compatible outputs.

Feature Summary

• Zero Delay Buffer IC with 1:5 input-to-output ratio
• Maximum operating frequency of 133.33 MHz
• Operates within a 3V to 3.6V voltage range
• Available in 8-SOIC surface-mount package

Applications

• SDRAM clock distribution
• Telecommunications systems
• Datacom equipment
• PC motherboards and workstations
• Critical path delay designs

Procurement Notes

Verify the specific suffix 'NZ' against official Renesas documentation to confirm compliance with RoHS directives and lead-free specifications. Confirm that the 8-SOIC package dimensions match the required PCB footprint. Ensure the commercial temperature range (0°C to 70°C) aligns with the target application environment before procurement.

Selection Notes

Select this component when a zero-delay clock buffer with five outputs is required for frequencies up to 133.33 MHz. It is suitable for systems needing low-skew clock distribution from a single reference source. Compare against the standard 2305-1 series if industrial temperature ratings (-40°C to 85°C) are necessary, as the NZ variant typically denotes commercial grade.

Part Context

The 2305NZ-1HDCG8 belongs to the Renesas 2305 family of zero-delay buffers. This family is characterized by low phase noise and high-speed PLL-based performance. The device is part of Renesas's broader portfolio of clock and timer ICs, derived from IDT technology acquired by Renesas Electronics Corporation.

Replacement Considerations

The 2305-1DCG8 is a related variant within the same family. Verify if the industrial temperature rating or different packaging options of the 2305-1DCG8 meet the design requirements. Cross-reference pinouts and electrical characteristics to ensure compatibility.
