2305-1DCGI

Overview

The Renesas Electronics 2305-1DCGI is a zero-delay buffer IC designed for clock distribution applications. It operates within a supply voltage range of 3V to 3.6V and supports maximum output frequencies up to 133 MHz. The device features one input and five outputs, packaged in an 8-SOIC format with dimensions of 4.9 x 3.9 x 1.5 mm. It functions within an industrial temperature range of -40°C to +85°C. Key electrical specifications include a maximum propagation delay of 0 ps and a typical output skew of less than 250 ps. The component utilizes an advanced sub-micron CMOS process and includes tri-state capabilities for board-level testing.

Feature Summary

• Zero-delay buffering using proprietary low jitter PLL techniques
• Five LVCMOS outputs with 25 mA drive capability at TTL levels
• Input frequency range from 10 MHz to 133 MHz
• Tri-state mode support for board-level testing

Applications

• High-speed clock distribution systems
• Telecommunications equipment
• Datacom infrastructure
• PC motherboards and workstations

Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C) compared to commercial variants. Confirm package type is 8-SOIC. Check RoHS compliance status as per current manufacturer documentation. Ensure compatibility with 3.3V logic levels for both input and output interfaces.

Selection Notes

Select this component when zero input-to-output delay is critical for system timing. Ensure the design requires five clock outputs driven by a single reference. Verify that the operating environment falls within the -40°C to +85°C range. Confirm power supply constraints align with the 3V to 3.6V specification.

Part Context

This part belongs to the IDT/Renesas 2305 series of zero-delay buffers. It is functionally similar to the 2305-1HDCGI but lacks the high-drive enhancement found in the 'H' variant. The base model 2305-1 serves as the foundation for this family, offering standard drive strength suitable for most digital logic loads.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other members of the 2305 family, such as 2305-1DCG or 2305-1HDCGI, only if temperature grades and drive requirements match.
