9FGV0831CKILFT

Overview

The 9FGV0831CKILFT is an eight-output clock generator designed for PCI Express applications. It operates within a supply voltage range of 1.7V to 1.9V and supports a maximum output frequency of 100MHz. The device features HCSL and LVCMOS output types, utilizing a crystal input with a 1:9 input-to-output ratio. Packaged in a 48-VFQFPN exposed pad format, it functions across an operating temperature range of -40°C to +85°C. This component integrates PLL circuitry to generate precise timing signals required for high-speed serial interface synchronization.

Feature Summary

• Eight differential outputs supporting PCIe Gen 1-2-3 standards
• Ultra-low power consumption typical of 1.5V PCIe clock families
• Programmable slew rate and output amplitude for signal integrity tuning
• Integrated spread spectrum capability to reduce EMI

Applications

• PCI Express (PCIe) Gen 1, 2, and 3 systems
• High-performance computing servers
• Storage subsystems requiring low-jitter clocking

Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging versus the 'LF' tray variant. Confirm moisture sensitivity level and reflow soldering profile requirements during assembly. Ensure the 48-VFQFPN footprint matches the PCB layout specifications. Check for end-of-life status or alternative part recommendations from the manufacturer.

Selection Notes

Select this component when eight synchronized low-power outputs are required for PCIe architectures. Verify that the 1.8V core voltage aligns with system power rails. Consider the 100MHz maximum frequency against specific bus speed requirements. Evaluate thermal dissipation needs given the compact VFQFPN package size.

Part Context

This model belongs to Renesas' ultra-low-power PCIe clock generator family. It serves as a direct replacement for legacy IDT clock solutions acquired by Renesas. The device simplifies board design by integrating termination resistors and eliminating external components typically needed for standard PCIe clock generators.

Replacement Considerations

The 9FGU0831CKILF is a documented substitute offering similar functionality. Verify pin compatibility and software configuration settings before substitution. Ensure the replacement meets the same PCIe generation and jitter specifications.
