9DB104BGLF

Application Specific Clock/Timing Overview

The 9DB104BGLF is a clock buffer integrated circuit manufactured by Renesas Electronics, designed for PCI Express (PCIe) applications. It features a single differential input and four differential outputs, supporting maximum frequencies up to 220 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and is housed in a 28-SSOP package. It includes an internal Phase-Locked Loop (PLL) for clock generation and buffering. The component is rated for commercial operating temperatures between 0°C and +70°C.

Application Specific Clock/Timing Feature Summary

• Four differential outputs with a 1:4 input-to-output ratio
• Integrated PLL for clock signal generation and distribution
• Supports PCIe timing requirements with maximum frequency of 220 MHz
• Operates on a 3.3V nominal supply voltage (3.135V–3.465V)

Application Specific Clock/Timing Applications

• PCI Express (PCIe) system clock distribution
• High-speed digital interface timing solutions
• Server and storage backplane clock buffering

Application Specific Clock/Timing Procurement Notes

The 9DB104BFLF variant is listed as obsolete with End-of-Life notices dated January and February 2022. Verification of the specific 'BGLF' suffix status is required against official Renesas documentation, as distributor data primarily references the 'BFLF' version. Confirm current production status and RoHS compliance directly with the manufacturer before procurement planning.

Application Specific Clock/Timing Selection Notes

Select this component for designs requiring a buffered PCIe clock source with low skew and jitter performance. Ensure the design accommodates the 28-SSOP package dimensions and the specific 3.3V power supply constraints. Verify that the 220 MHz maximum frequency meets the target bus speed requirements.

Application Specific Clock/Timing Part Context

This part belongs to the 9DB104 series of PCIe clock buffers. It serves as a timing solution for generating and distributing reference clocks in high-speed serial interfaces. The device integrates PLL functionality to clean and multiply input clock signals for downstream components.

Application Specific Clock/Timing Replacement Considerations

Renesas recommends the 9ZXL0451EKILFT as a replacement for the 9DB104BFLF. Verify pinout and electrical compatibility if substituting.
