9DB108BGLF

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 9DB108BGLF is a PCI Express (PCIe) clock buffer and driver IC designed for high-speed digital systems. It features an integrated Phase-Locked Loop (PLL) to generate differential outputs from a single differential input, providing a 1:8 output ratio. The device supports maximum frequencies up to 220 MHz and operates within a supply voltage range of 3.135 V to 3.465 V. Packaged in a 48-TFSOP surface-mount format, it is intended for applications requiring precise timing distribution in PCIe architectures.

Application Specific Clock/Timing Feature Summary

• Integrates a PLL for jitter attenuation and clock generation
• Converts one differential input to eight differential outputs
• Supports maximum operating frequency of 220 MHz
• Operates on a single 3.3V power supply (3.135V–3.465V)

Application Specific Clock/Timing Applications

• PCI Express (PCIe) system clock distribution
• High-performance server and storage backplanes
• Network infrastructure equipment

Application Specific Clock/Timing Procurement Notes

The 9DB108BGLF has reached the end-of-life (EOL) status and is no longer manufactured by Renesas Electronics. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory channels. Designers should initiate replacement strategies immediately due to discontinuation.

Application Specific Clock/Timing Selection Notes

When selecting this component, verify that the 48-TFSOP package dimensions match the PCB footprint requirements. Ensure the design accommodates the specific 3.3V supply tolerance and thermal dissipation needs for surface-mount installation. Confirm that the 220 MHz frequency capability aligns with the target PCIe generation specifications.

Application Specific Clock/Timing Part Context

This part belongs to the 9DB108 family of PCIe clock buffers. It shares functional similarities with other members like the 9DB108BFLF but differs in packaging. The BGLF suffix specifically denotes the 48-TFSOP package variant, distinguishing it from SSOP or TSSOP options within the same product line.

Application Specific Clock/Timing Replacement Considerations

Public records indicate the 9DB803DGLF as a similar alternative offered by Renesas Electronics. Verify pin compatibility and electrical specifications before substitution.
