9FGL0451BKILFT

Overview

The 9FGL0451BKILFT is a clock generator from the Renesas 9FGL0451 family, designed for high-speed serial link applications. It features four outputs with Low-Power HCSL (LP-HCSL) signaling and an output impedance of 100 ohms. The device operates on a single 3.3V supply voltage and supports input frequencies ranging from 25 MHz to 100 MHz. It utilizes a Phase-Locked Loop (PLL) architecture to generate precise clock signals. The component is housed in a 32-lead VFQFPN package (5.0mm x 5.0mm) and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Four LP-HCSL differential outputs with 100-ohm impedance
• Supports PCIe Gen1 through Gen6 jitter compliance
• Integrated PLL with spread spectrum capability
• Single 3.3V power supply operation

Applications

• PCI Express (PCIe) Gen1–Gen6 clock generation
• SerDes clock distribution
• High-speed data communication systems

Procurement Notes

Verify availability status as the related tray-packaged variant (9FGL0451BKILF) is listed as discontinued by major distributors. Confirm lead times and end-of-life notifications directly with Renesas Electronics or authorized partners before design finalization.

Selection Notes

Select this component for designs requiring low-jitter LP-HCSL outputs for PCIe applications. Ensure the system board layout accommodates the 32-lead VFQFPN package dimensions. Verify that the input source matches the supported frequency range of 25 MHz to 100 MHz.

Part Context

This part belongs to the 9FGL0451 series of clock generators. It shares architectural similarities with other members like the 9FGL0441DKILF but differs in packaging and specific output configurations. The 'T' suffix typically indicates tape-and-reel packaging, distinct from the tray packaging of the non-T variant.

Replacement Considerations

Check for direct pin-to-pin replacements within the 9FGL0451 family. Evaluate alternative clock generators from Renesas or other vendors if the 9FGL0451BKILFT is unavailable, ensuring compatibility with LP-HCSL signaling and PCIe jitter requirements.
