2305-1HDCG8

Overview

The Renesas 2305-1HDCG8 is a zero-delay clock buffer featuring a Phase-Locked Loop (PLL) for low phase noise and high-speed performance. It provides five LVCMOS outputs with a maximum frequency of 133 MHz and zero input-to-output propagation delay. The device operates on a single 3V to 3.6V supply within an industrial temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC, it supports tri-state modes and includes features such as device-to-device skew control and full CMOS output drive capabilities.

Feature Summary

• Zero Delay Buffer: PLL-based architecture ensures zero input-to-output propagation delay.
• High-Speed Performance: Supports clock frequencies up to 133 MHz with low skew outputs.
• Industrial Temperature Range: Rated for operation between -40°C and +85°C.
• Single Supply Operation: Functions with a voltage range of 3V to 3.6V.

Applications

• Clock distribution in high-speed digital systems
• Buffering reference clocks for processors or memory interfaces
• Low-skew timing synchronization in communication equipment

Procurement Notes

Verify the specific suffix 'GI8' against official Renesas documentation to confirm the package type and temperature grade. Confirm RoHS compliance status directly from the manufacturer's current datasheet revision, as regulatory status can change. Ensure the ordering information matches the exact part number to avoid discrepancies in lead times or packaging quantities.

Selection Notes

Select this component when zero input-to-output delay is critical for system timing. The 2305-1HDCG8 is suitable for applications requiring five buffered outputs from a single source. Compare the 133 MHz maximum frequency against system requirements. Verify that the 3.3V logic levels are compatible with downstream components.

Part Context

This part belongs to the IDT 2305 family of zero-delay buffers. The '1H' designation indicates a high-drive version with faster rise and fall times compared to the base model. The 'GI8' suffix specifies the 8-pin SOIC package and the industrial temperature rating. This series is designed for low jitter clock distribution.

Replacement Considerations

The IDT2305-1DCG8 is a related variant within the same family but typically differs in temperature range or drive strength specifications. Cross-reference the exact electrical parameters and package dimensions before substitution. No direct public substitute part numbers are confirmed for this specific suffix combination.
