9DB108BGLFT

Overview

The 9DB108BGLFT is a PCI Express (PCIe) clock buffer and driver manufactured by Renesas Electronics. It features a single input to eight output configuration with differential input and output capabilities. The device supports maximum frequencies of 220 MHz and operates on a supply voltage range of 3.135 V to 3.465 V. Packaged in a 48-TFSOP (TSSOP) surface-mount case, it includes an internal PLL for clock generation. The component is designed for timing applications within PCIe systems.

Feature Summary

• 1:8 Input-to-Output Ratio
• Differential Input and Output Signals
• Internal Phase-Locked Loop (PLL)
• Maximum Frequency of 220 MHz

Applications

• PCI Express (PCIe) Clock Distribution
• Intel CPU Server Timing
• SATA Clock Generation

Procurement Notes

This component has been officially discontinued and is no longer in production. Verification of availability should focus on obsolete stock or authorized distributors holding remaining inventory. Engineering change notices indicate end-of-life status effective March 2022. Designers must confirm the finality of the discontinuation notice before proceeding with procurement plans.

Selection Notes

Select this part only for legacy designs requiring a 220 MHz PCIe clock buffer with a 1:8 ratio. Verify that the 48-TFSOP package dimensions match the existing PCB footprint. Ensure the system power supply remains within the 3.135 V to 3.465 V operating range. Consider alternative components if new design rules prohibit obsolete parts.

Part Context

The 9DB108BGLFT belongs to the 9DB108 series of clock buffers from Renesas. It shares functional similarities with other members like the 9DB108BFLF but differs in packaging. The BGLFT suffix denotes the specific TSSOP-48 package and lead-free compliance. This model was widely used in server and storage controller boards prior to its discontinuation.

Replacement Considerations

Public records list the 9DB803DGLF as a similar replacement option. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
