2305-1DCG

Overview

The Renesas Electronics Corporation 2305-1DCG is a Zero Delay Buffer IC operating at frequencies up to 133MHz. It features a 1:5 input-to-output ratio and accepts LVTTL inputs while providing CMOS, LVCMOS, or TTL outputs. The device operates on a 3V to 3.6V supply voltage within an industrial temperature range of -40°C to 85°C. Packaged in an 8-SOIC format with a width of 3.90mm, it utilizes a PLL with bypass functionality for clock distribution.

Feature Summary

• Zero delay buffer architecture utilizing low phase noise PLL techniques
• Supports full CMOS outputs with high drive capability at TTL levels
• Includes tri-state mode for board-level testing and direct input bypass

Applications

• Clock distribution in SDRAM systems
• Telecommunications equipment
• Datacom applications
• PC motherboards and workstations
• Critical path delay designs

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with system voltage requirements and input signal standards before integration. Cross-reference manufacturer part numbers to avoid confusion with similar variants in the 2305 series.

Selection Notes

Select this component when zero input-output delay is required for high-speed clock distribution. It is suitable for applications needing multiple low-skew outputs from a single reference. Consider the 8-SOIC package constraints and industrial temperature range suitability for the target environment.

Part Context

This component belongs to the 2305 series of low skew zero delay buffers manufactured by Renesas Electronics. It is based on IDT's proprietary low jitter Phase Locked Loop techniques. The device provides four low skew outputs plus one additional output, designed for speeds up to 133MHz at 3.3V operation.

Replacement Considerations

IDT2305-1DCGI8 is a verified substitute offering identical electrical characteristics with an extended industrial temperature range.
