9FGV0641AKILF

Overview

The Renesas 9FGV0641AKILF is a six-output PCIe clock generator designed for Gen1 through Gen3 applications. It operates on a 1.8V supply with typical power consumption of 54 mW. The device accepts a 25 MHz external crystal input and generates LP-HCSL outputs with integrated 100-ohm terminations, eliminating the need for external resistors. It supports spread spectrum modulation to reduce EMI and features programmable slew rates and amplitudes. The component is housed in a compact 5x5 mm 40-pin VFQFPN package.

Feature Summary

• Six LP-HCSL outputs with integrated 100-ohm terminations for direct connection to transmission lines
• Low power consumption of 54 mW typical with optional output voltage scaling between 1.05V and 1.8V
• Programmable slew rate and amplitude tuning for various line lengths and environments
• Supports selectable spread spectrum levels (0%, -0.25%, -0.5%) to minimize EMI

Applications

• PCI Express Gen1, Gen2, and Gen3 systems
• Server and workstation motherboard clocking
• High-performance computing platforms

Procurement Notes

Verify the specific suffix 'KILF' against the manufacturer's official documentation to confirm packaging details and RoHS compliance status. Ensure the required 25 MHz external crystal is sourced separately as it is not included with the device. Confirm that the 40-VFQFPN package dimensions align with the target PCB layout constraints.

Selection Notes

Select this component when designing for PCIe Gen1-3 interfaces requiring low power and minimal board space. It is suitable for systems needing integrated output termination to reduce BOM count. Consider the 1:7 ratio if additional fanout beyond the six differential outputs is required elsewhere in the design. Verify SMBus interface compatibility with existing system controllers for configuration management.

Part Context

This part belongs to IDT's SOC-Friendly 1.8V Very-Low-Power PCIe clock family, now under Renesas Electronics. It is engineered to provide direction connection to 100-ohm transmission lines while saving board space compared to standard PCIe devices. The device supports DIF power management via OE# pins and ensures clean system start-up by blocking outputs until the PLL is locked.
