5T905PGGI

Overview

The 5T905PGGI is a 2.5V single data rate (SDR) clock buffer from the TeraBuffer family, manufactured by Renesas Electronics. It features a user-selectable input configuration supporting both single-ended and differential signals, driving five single-ended outputs. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports an input frequency up to 200 MHz. It is housed in a 28-TSSOP package with a width of 4.40 mm. The component functions as a fanout buffer for clock distribution, offering low propagation delay characteristics suitable for high-performance digital systems.

Feature Summary

• Supports user-selectable single-ended or differential input configurations
• Drives five single-ended output channels for clock distribution
• Operates on a 2.5V power supply with wide voltage tolerance
• Compatible with eHSTL, HSTL, LVPECL, and LVTTL signaling standards

Applications

• High-speed data bus clock distribution
• Memory subsystem timing synchronization
• Single data rate (SDR) system architecture buffering
• Differential-to-single-ended signal conversion

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the 28-TSSOP package dimensions align with existing PCB footprints. Ensure that the 2.5V operating voltage matches the target system's power rails. Check for available lifecycle management options or recommended replacements if long-term supply is required.

Selection Notes

Select this buffer when a 1:5 fanout ratio is required for SDR applications. It is appropriate for systems needing flexible input options between single-ended and differential sources. Consider the 200 MHz maximum input frequency limit for timing requirements. Evaluate the 28-TSSOP package size against board space constraints.

Part Context

This part belongs to the 5T905 series of TeraBuffer clock drivers. It is designed for high-performance clock distribution in digital logic circuits. The device provides signal integrity improvements over standard buffers by managing skew and jitter in high-speed environments. It serves as a critical interface component between source clocks and multiple destination loads.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, alternative sourcing should focus on inventory availability or design-in of newer generation buffers with compatible pinouts and electrical specifications.
