2305B-1DCGI8

Overview

The Renesas Electronics Corporation 2305B-1DCGI8 is a high-speed phase-locked loop (PLL) clock buffer designed for zero-delay clock distribution. It operates with a single 3.3 V power supply and features one LVCMOS input driving five LVCMOS outputs. The device supports maximum frequencies up to 133 MHz within an operating temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, it ensures precise timing alignment by eliminating propagation delay between the input and output clocks.

Feature Summary

• Zero-delay operation achieved through internal PLL feedback mechanism
• Single-ended LVCMOS input and output signal compatibility
• High-speed performance supporting frequencies up to 133 MHz
• Industrial temperature rating for extended operational reliability

Applications

• High-speed clock distribution networks
• System-on-chip clock generation and buffering
• Digital signal processing timing synchronization
• Communication equipment clock management

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Renesas documentation. Confirm that the suffix 'GI8' corresponds to the specified industrial temperature range and SOIC package variant. Ensure compliance with RoHS3 standards as indicated in public specifications. Validate supply chain sources against authorized distributor lists to prevent counterfeit components. Review datasheet revisions for any recent design or assembly changes.

Selection Notes

Select this component when zero-propagation-delay clock buffering is required for LVCMOS interfaces. The 1:5 output ratio suits applications needing multiple synchronized clock lines from a single source. Consider the 8-SOIC package constraints for PCB layout and thermal management. Verify that the 3.3 V supply voltage aligns with the system power architecture. Assess jitter specifications against target application requirements for signal integrity.

Part Context

This device belongs to the Renesas 2305 series of zero-delay buffers. It serves as a critical timing element in digital systems requiring precise clock alignment. The series is characterized by low skew and high-frequency operation. The specific model integrates PLL functionality to lock output phase to the input reference, ensuring stable clock distribution without added latency compared to standard buffer solutions.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT2305-1DCGI8 and IDT2305-1HDCGI8. These alternatives share identical functional characteristics and pinouts within the same product family. Verify package dimensions and electrical parameters before substitution. Ensure that the replacement matches the required temperature grade and supply voltage specifications.
