9DB104BGLFT

Application Specific Clock/Timing Overview

The Renesas Electronics Corporation 9DB104BGLFT is a clock buffer IC designed for PCI Express (PCIe) applications. It features a single input and four outputs, supporting a maximum frequency of 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 with a width of 5.30 mm. It functions across a commercial temperature range from 0°C to +70°C. The component includes an internal PLL and is RoHS3 compliant.

Application Specific Clock/Timing Feature Summary

• Four differential outputs with HCSL/LVDS compatibility
• Maximum operating frequency of 220 MHz
• Integrated Phase-Locked Loop (PLL)
• Surface-mount 28-SSOP package

Application Specific Clock/Timing Applications

• PCI Express clock distribution
• High-speed communication systems
• Server motherboard clocking

Application Specific Clock/Timing Procurement Notes

The 9DB104BFLF variant is listed as obsolete by the manufacturer. Verification of the specific 'BGLFT' suffix status is required as datasheets primarily reference the BFLF version. Confirm current lifecycle status and availability through authorized channels before design-in.

Application Specific Clock/Timing Selection Notes

Select this component for PCIe designs requiring a 1:4 fanout buffer. Ensure the system power supply maintains the 3.135 V to 3.465 V range. Verify that the 28-SSOP footprint matches the PCB layout constraints and that the 220 MHz frequency limit meets the target bus speed requirements.

Application Specific Clock/Timing Part Context

This part belongs to the 9DB104 series of clock buffers. It serves as a signal integrity solution for distributing reference clocks in high-speed digital interfaces. The device is manufactured by Renesas Electronics Corporation, formerly Integrated Circuit Systems (ICS).

Application Specific Clock/Timing Replacement Considerations

The 9ZXL0451EKILFT is listed as a manufacturer-recommended replacement for the 9DB104BFLFT. Verify pinout and electrical parameter compatibility when substituting.
