9FGU0641AKLF

Overview

The 9FGU0641AKLF is a six-output clock generator designed for PCIe Gen1-3 applications. It operates at a supply voltage of 1.5V with an input frequency range up to 27MHz and maximum output frequency of 100MHz. The device features integrated 100Ω output terminations, low jitter of 50ps, and consumes 6mA operating current. It supports HCSL output levels and is housed in a 40-VFQFN package.

Feature Summary

• Integrated 100Ω output termination for simplified PCB layout
• Ultra-low power consumption suitable for portable designs
• Low jitter performance ensuring signal integrity
• HCSL output compatibility with standard interfaces

Applications

• PCI Express Gen1-3 clock generation
• Server and workstation motherboard design
• Portable computing devices requiring low power clocks
• Industrial control systems with PCIe connectivity

Procurement Notes

Verify the specific suffix 'AKLF' matches your required packaging and temperature grade. Confirm RoHS compliance status through official Renesas documentation. Ensure the 40-VFQFN package dimensions align with your PCB footprint requirements. Check for any lead-free soldering constraints if applicable to your manufacturing process.

Selection Notes

Choose this component when six synchronized outputs are required for PCIe lanes. Consider the 1.5V supply constraint against system power rails. Evaluate the 50ps jitter specification against receiver sensitivity requirements. Compare the VFQFN package size against available board space constraints.

Part Context

This part belongs to Renesas' ultra-low power PCIe clock generator family. It complements higher voltage variants like the 9FGV series. The device targets modern high-speed serial link applications where power efficiency and signal quality are critical parameters for system stability.

Replacement Considerations

Direct substitutes include other 6-output 1.5V PCIe clock generators from Renesas such as the 9FGU0841AKLF for additional outputs. Cross-reference pinout compatibility before replacing with non-Renesas alternatives. Verify electrical specifications match exactly to ensure signal integrity.
