9FGV1005CQ501LTGI8

Overview

The 9FGV1005CQ501LTGI8 is a programmable clock generator from Renesas' PhiClock™ family, designed for Ethernet and PCI Express applications. It features a single circuit with a 1:3 input-to-output ratio and supports maximum frequencies up to 325MHz. The device accepts HCSL, LVCMOS, LVDS, or crystal inputs and provides CML, HCSL, LP-HCSL, LVCMOS, LVDS, or LVPECL outputs. Operating on a supply voltage of 1.71V to 3.465V, it functions within a temperature range of -40°C to 85°C. The component is housed in a 16-TFLGA exposed pad package.

Feature Summary

• Programmable PhiClock™ architecture supporting PCIe Gen1-Gen4 jitter compliance
• Flexible I/O standards including LP-HCSL, LVDS, and LVPECL
• Single PLL circuit with 1:3 output ratio
• Wide supply voltage range of 1.71V to 3.465V

Applications

• PCI Express (PCIe) clock generation
• Ethernet interface timing
• High-speed digital system synchronization

Procurement Notes

Verify the specific suffix LTGI8 against official Renesas documentation to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with existing board layouts for the 16-LGA(3x3) footprint. Confirm that the factory-configured settings match the required frequency and protocol specifications before integration.

Selection Notes

Select this model when a fixed 1:3 ratio is required for PCIe or Ethernet designs. The 16-TFLGA package suits space-constrained applications. Verify that the supported output formats (LP-HCSL, LVDS, etc.) align with the downstream receiver requirements. Check if the integrated crystal option is necessary or if an external oscillator is preferred.

Part Context

This component belongs to the 9FGV100xC series of programmable clock generators. It shares architectural similarities with other PhiClock devices but is distinguished by its specific factory configuration for 325MHz operation and 1:3 ratio. It serves as a specialized timing solution for high-speed serial interfaces requiring low jitter performance.

Replacement Considerations

Direct replacements include other 9FGV1005 variants with compatible pinouts and electrical characteristics. Verify that alternative part numbers support the same 16-LGA package and output standards. Cross-reference datasheets to ensure identical jitter performance and supply voltage ranges.
