2305-1HDCGI8

Overview

The Renesas 2305-1HDCGI8 is a zero-delay clock buffer IC designed for high-speed digital systems. It operates on a single 3V to 3.6V supply and features one LVCMOS input driving five LVCMOS outputs. The device utilizes an internal PLL to achieve zero propagation delay between the input and output clocks, with a maximum operating frequency of 133 MHz. Packaged in an 8-pin SOIC (0.154 inch width) for surface-mount applications, it supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Zero Delay Buffer: Internal PLL feedback ensures minimal input-to-output propagation delay.
• High-Speed Performance: Supports clock frequencies up to 133 MHz with low skew characteristics.
• LVCMOS Interface: Compatible with standard logic families via LVCMOS input and output types.
• Industrial Reliability: Operates within a wide temperature range of -40°C to +85°C.

Applications

• Clock distribution networks requiring precise timing alignment.
• High-speed data acquisition systems.
• Telecommunications equipment clock synchronization.
• Digital signal processing boards.

Procurement Notes

Verify RoHS compliance status through official Renesas documentation or authorized distributor datasheets prior to procurement. Confirm that the specific suffix 'GI8' corresponds to the required industrial temperature grade (-40°C to +85°C) and SOIC-8 packaging variant. Ensure compatibility with 3.3V logic levels for both power supply and I/O signals.

Selection Notes

Select this component when zero propagation delay is critical for system timing integrity. The 2305-1HDCGI8 is suitable for designs requiring a single differential or single-ended input to fan-out to five outputs at speeds up to 133 MHz. Ensure the PCB layout accommodates the 8-SOIC package dimensions (4.9 x 3.9 mm) and that the power supply voltage remains strictly within the 3V to 3.6V operational window.

Part Context

This part belongs to the IDT 2305 series of zero-delay buffers, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas Electronics. The series is characterized by low phase noise and low skew performance, making it a standard solution for clock buffering in legacy and current high-performance computing architectures.

Replacement Considerations

The 2305-1DCGI8 is a verified alternative within the same family, offering identical electrical specifications but potentially differing in manufacturing lot or minor suffix variations. Verify pinout compatibility and ensure the replacement meets the same 3.3V LVCMOS requirements.
