9DB108BFLFT

Application Specific Clock/Timing Overview

The Renesas 9DB108BFLFT is a PCI Express (PCIe) clock buffer and driver IC designed for high-speed digital applications. It features an integrated Phase-Locked Loop (PLL) and operates at a maximum frequency of 220MHz with a single input to eight output configuration. The device utilizes HCSL output drivers and supports differential input/output signaling. It functions within a supply voltage range of 3.135V to 3.465V and is rated for commercial temperatures from 0°C to 70°C. The component is housed in a 48-TFSOP package.

Application Specific Clock/Timing Feature Summary

• PCI Express Zero-Delay Buffer with integrated PLL
• 1:8 Input-to-Output Ratio supporting up to 220MHz
• Differential Input and Output capabilities
• HCSL Output Driver technology

Application Specific Clock/Timing Applications

• PCI Express (PCIe) systems
• High-performance computing platforms
• Server infrastructure clock distribution

Application Specific Clock/Timing Procurement Notes

This component is officially classified as End-of-Life (EOL) by the manufacturer. Production ceased on March 24, 2022, according to Product Change Notification records. Verification of authenticity is critical when sourcing remaining stock, as availability is limited to existing inventory or surplus channels. Designers should initiate replacement strategies immediately due to the discontinued status.

Application Specific Clock/Timing Selection Notes

Engineers selecting this part must account for its EOL status and plan for obsolescence management. The 48-TFSOP package dimensions are 0.240 inches wide. Compatibility checks should focus on the 1:8 fan-out ratio and 220MHz operational limit. Alternative components must match the HCSL output type and differential signaling requirements of the target PCIe architecture.

Application Specific Clock/Timing Part Context

The 9DB108BFLFT belongs to the 9DB108 family of PCIe clock buffers. It shares functional similarities with other members like the 9DB104BFLFT (1:4 ratio) but provides higher fan-out capability. The 'FLFT' suffix indicates the specific tape-and-reel packaging and lead-free compliance standard used in this variant.

Application Specific Clock/Timing Replacement Considerations

Public documentation lists the RC19008A100GND#KB as a potential substitute option.
