9FGU0441AKLF

Application Specific Clock/Timing Overview

The Renesas 9FGU0441AKLF is a four-output clock generator designed for PCI Express (PCIe) Gen1, Gen2, and Gen3 applications. It operates on a single 1.5V supply voltage and features a 32-pin VFQFPN package. The device supports LVDS or crystal inputs and provides LP-HCSL and LVCMOS outputs. It includes an integrated PLL for frequency synthesis and offers reference output capabilities with SMBus address selection via latch.

Application Specific Clock/Timing Feature Summary

• Generates low-power PCIe clocks for multiple generations
• Supports differential LVDS or single-ended crystal inputs
• Provides flexible LP-HCSL and LVCMOS output configurations
• Integrates PLL for precise frequency generation

Application Specific Clock/Timing Applications

• PCI Express Gen1/Gen2/Gen3 clock distribution
• Server and storage system timing
• High-speed interface synchronization

Application Specific Clock/Timing Procurement Notes

Verify the specific suffix 'AKLF' to ensure compatibility with tray packaging and 32-pin VFQFPN form factor. Confirm that the required output types match the device's LP-HCSL and LVCMOS capabilities. Check for any regional compliance requirements regarding RoHS specifications before finalizing procurement orders.

Application Specific Clock/Timing Selection Notes

Select this component when designing systems requiring synchronized PCIe clock signals across multiple lanes. Ensure the input source matches either LVDS or crystal options. Verify that the 1.5V operating voltage aligns with the system's power rails. Consider the thermal performance within the specified 0°C to +70°C range for industrial environments.

Application Specific Clock/Timing Part Context

This part belongs to Renesas' specialized clock generator family tailored for high-speed serial interfaces. It complements other devices like the 9DBV0241 buffer by providing the primary clock source. The series focuses on low power consumption and signal integrity for modern computing architectures.

Application Specific Clock/Timing Replacement Considerations

The 9FGV0441AKILFT is a related variant but differs in packaging and potentially pinout. Direct substitution requires verification of electrical characteristics and mechanical fit. Consult official cross-reference guides to confirm functional equivalence without redesigning the PCB layout.
