9DB108BGLFT-INT

Overview

The 9DB108BGLFT-INT is a PCI Express (PCIe) clock buffer and driver manufactured by Renesas Electronics Corporation. It features an integrated Phase-Locked Loop (PLL) to generate eight differential outputs from a single differential input, providing a 1:8 distribution ratio. The device supports maximum frequencies up to 220MHz and operates within a supply voltage range of 3.135V to 3.465V. Designed for surface mount installation, it is housed in a 48-TFSOP package with a width of 6.10mm. The component is rated for operation at temperatures between 0°C and 70°C.

Feature Summary

• Integrates a PLL for low-jitter clock generation
• Provides one differential input driving eight differential outputs
• Supports PCIe applications with frequencies up to 220MHz
• Operates on a single 3.3V power supply

Applications

• PCI Express (PCIe) system clock distribution
• High-speed data communication interfaces
• Server and storage backplane timing

Procurement Notes

The 9DB108BGLFT-INT part number indicates an industrial temperature grade variant (-40°C to +85°C), whereas the standard 9DB108BGLFT is rated for commercial temperatures (0°C to 70°C). Verification against official Renesas documentation is required to confirm if this specific suffix exists or if it represents a custom designation. Cross-reference the exact electrical specifications and pinout compatibility before procurement.

Selection Notes

Select this component when designing PCIe architectures requiring a single source to drive multiple receivers with precise phase alignment. Ensure the design accommodates the 48-pin TSSOP footprint and the 3.3V power domain. Verify that the required operating temperature range matches the specific suffix designation, as standard versions may not support extended industrial conditions.

Part Context

This component belongs to the 9DB108 family of clock buffers. It serves as a replacement for legacy clock generators in high-speed digital systems. The 'GLFT' suffix denotes the 48-TFSOP package and lead-free construction. The '-INT' suffix typically signifies an industrial temperature rating, distinguishing it from the commercial grade standard version.

Replacement Considerations

The 9DB803DGLF is listed as a similar alternative by distributors. Verify functional equivalence regarding output count, jitter performance, and package dimensions before substitution.
