2305NZ-1HDCGI8

Overview

The Renesas 2305NZ-1HDCGI8 is a clock buffer IC designed for high-speed clock distribution. It accepts one reference input and drives five low-skew outputs. The device operates within a supply voltage range of 2.3 V to 2.7 V, supporting frequencies up to 133 MHz. It features a maximum propagation delay of 8.7 ns and utilizes LVCMOS output types. Packaged in an 8-SOIC format, it supports surface-mount installation and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Five LVCMOS outputs with a maximum frequency of 133 MHz
• Operates on a 2.3 V to 2.7 V power supply
• Maximum propagation delay of 8.7 ns
• Available in an 8-SOIC package

Applications

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

Procurement Notes

Verify the specific suffix 'NZT' against the requested model '2305NZ-1HDCGI8'. Public records indicate the 'NZT' series typically denotes the 2.5V variant (2.3V–2.7V) in SOIC-8 packaging. Confirm that the required operating temperature range matches the commercial specification (0°C to +70°C) rather than industrial grades. Ensure the pinout and electrical characteristics align with the target design requirements before procurement.

Selection Notes

Select this component when a 2.5V logic interface is required for clock distribution. The 8.7 ns propagation delay distinguishes it from zero-delay buffers which offer near-zero latency. Verify that the 5-output configuration meets the system's fan-out needs. Ensure the PCB layout accommodates the 8-SOIC footprint with a 1.27 mm pitch.

Part Context

This part belongs to the 2305NZT family of clock buffers. It serves as a non-zero delay alternative to the zero-delay 2305 series. The device is manufactured by Renesas Electronics Corporation, formerly IDT. It is categorized under Clock & Timer ICs and is distinct from the higher-voltage 3.3V variants found in the standard 2305 line.

Replacement Considerations

Public data lists IDT2305NZT-1DCG as an alias. Direct substitutes within the same voltage and package constraints are not explicitly confirmed in the provided source material.
