9FGV0841AKLFT

Overview

The Renesas 9FGV0841AKLFT is a clock generator designed for PCI Express applications. It features a single circuit with a 1:9 input-to-output ratio, accepting crystal inputs to generate up to 100MHz output frequencies. The device supports HCSL and LVCMOS output types without differential signaling. It operates on a 1.7V to 1.9V supply voltage within a 0°C to 70°C temperature range. Packaged in a 48-VFQFN exposed pad (6x6mm) for surface mount installation, it includes an integrated PLL for frequency synthesis.

Feature Summary

• Supports PCI Express clock generation with 100MHz maximum frequency
• Provides 9 outputs via HCSL and LVCMOS logic levels
• Integrates a Phase-Locked Loop (PLL) for timing stability
• Operates at low voltage (1.7V–1.9V) in a compact 48-VFQFN package

Applications

• PCI Express system clock distribution
• Computer motherboard timing circuits
• Peripheral interface clock generation

Procurement Notes

Verify the specific suffix 'KLFT' against the manufacturer datasheet to confirm tape-and-reel packaging and lead-free status. Ensure the 48-VFQFN footprint matches the PCB layout requirements. Confirm RoHS compliance documentation is available for regulatory adherence.

Selection Notes

Select this component when a PCIe-compatible clock source with nine outputs is required. Ensure the design accommodates the 1.7V to 1.9V power rail. Verify that HCSL or LVCMOS output compatibility aligns with the target receiver inputs.

Part Context

This part belongs to the Renesas clock generator family focused on high-speed serial interfaces. It serves as a timing reference for PCIe lanes, replacing discrete oscillator solutions with a programmable or fixed-frequency integrated approach.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas series. Verify if other packages like TSSOP are available for different assembly needs.
