2305-1DCGI8

Overview

The Renesas 2305-1DCGI8 is a zero-delay buffer integrated circuit 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 LVCMOS outputs, packaged in an 8-SOIC (0.154 inch width) surface-mount package. It exhibits a maximum propagation delay of 0 ps and functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Zero-delay PLL-based architecture ensures minimal input-to-output latency.
• Provides five low-skew LVCMOS outputs with drive capability at TTL levels.
• Operates on a single 3.3V power supply with sub-micron CMOS process technology.

Applications

• High-speed digital signal processing clock distribution
• FPGA and ASIC clock buffering systems
• Telecommunications equipment timing networks

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the '8' suffix indicates reel packaging rather than tube. Cross-reference the manufacturer part number IDT2305-1DCGI8 for legacy documentation compatibility. Ensure RoHS3 compliance requirements are met for the final assembly.

Selection Notes

Select this component when zero propagation delay is critical for system synchronization. The 8-SOIC package suits space-constrained surface-mount designs. Verify that the 133 MHz maximum frequency meets the target clock speed requirements. Ensure the 3V to 3.6V operating voltage aligns with the system power rail specifications.

Part Context

This part belongs to the 2305 series of zero-delay buffers manufactured by Renesas Electronics. It is functionally equivalent to the IDT2305-1DCGI8 designation. The device utilizes internal PLL feedback obtained from the CLKOUT pad to eliminate skew between the input and output clocks.

Replacement Considerations

The 2305-1DCG8 serves as a commercial grade alternative with a 0°C to 70°C operating range. The 2305-1HDCGI8 offers high-drive capabilities with faster rise and fall times while maintaining the same industrial temperature specifications.
