2305A-1HDCG8

Overview

The Renesas Electronics Corporation 2305A-1HDCG8 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 frequencies up to 133MHz. The device features a single circuit configuration with an LVTTL input and CMOS, LVCMOS, or TTL output types. Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount housing, it functions across an industrial temperature range of -40°C to +85°C. This component integrates a Phase Locked Loop (PLL) with bypass capability to ensure low skew performance.

Feature Summary

• Zero Delay Buffer architecture with PLL bypass capability
• Maximum operating frequency of 133MHz
• Supply voltage range of 3V to 3.6V
• Industrial temperature range from -40°C to +85°C

Applications

• Clock distribution in high-speed digital systems
• Low skew buffering for processor interfaces
• System timing synchronization

Procurement Notes

Verify the specific suffix '8' indicates reel packaging when sourcing. Confirm RoHS3 compliance status as per current manufacturer documentation. Check for End-of-Life notices or alternative part recommendations from Renesas due to potential product lifecycle changes. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component for applications requiring a 1:5 input-to-output ratio with zero delay characteristics. Ensure the system logic levels are compatible with LVTTL inputs and CMOS/LVCMOS/TTL outputs. Verify that the 3.3V nominal supply voltage aligns with the 3V-3.6V operational range. Consider the 8-pin SOIC package constraints for board layout and thermal management.

Part Context

This part belongs to the 2305A series of zero delay buffers from Renesas. It serves as a specialized clock buffer solution distinct from general-purpose oscillators. The 'A' variant typically denotes specific drive strength or feature sets compared to base models like the 2305-1. It is engineered for low phase noise and high-speed signal integrity in embedded systems.

Replacement Considerations

Renesas recommends the 2305A-1HDCGI as a potential substitute. Verify pin compatibility and electrical specifications before substitution.
