9FGV1005CQ506LTGI

Overview

The 9FGV1005CQ506LTGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for PCIe and Ethernet applications. It features an integrated PLL with input options including HCSL, LVCMOS, LVDS, and crystal. The device provides six outputs supporting CML, HCSL, LP-HCSL, LVCMOS, LVDS, and LVPECL signaling. Supply voltages are 1.71V–1.89V, 2.375V–2.625V, and 3.135V–3.465V. Operating temperature ranges from -40°C to 85°C. It is housed in a 24-lead LGA package (4.0x4.0mm) with exposed pad.

Feature Summary

• Programmable architecture with hardware select pins or I²C software configuration
• Supports multiple output signaling standards: CML, HCSL, LP-HCSL, LVCMOS, LVDS, LVPECL
• Compliant with PCIe Gen1 through Gen5 jitter specifications
• Four unique I²C addresses for multi-component system access

Applications

• PCI Express (Gen1–Gen5) timing solutions
• Ethernet interface clock generation
• Server and storage system clock distribution

Procurement Notes

Verify the specific suffix LTGI against the official datasheet to confirm package type and moisture sensitivity level. Confirm RoHS compliance status directly with the manufacturer documentation. Check current availability as stock levels fluctuate. Ensure the ordering quantity meets the manufacturer's standard packaging requirements.

Selection Notes

Select this component when a low-jitter, programmable clock source is required for high-speed serial interfaces like PCIe. Verify that the available supply voltage rails match the device's 1.8V, 2.5V, and 3.3V core requirements. Ensure the design accommodates the 24-LGA footprint and thermal pad soldering constraints.

Part Context

This part belongs to the 9FGV100xC series of PhiClock generators. It shares architectural similarities with models like 9FGV1002 and 9FGV1004 but differs in factory-programmed frequency configurations and output pin assignments. The 'CQ' suffix typically denotes specific frequency and package variations within the product line.

Replacement Considerations

Direct replacements within the same family include 9FGV1002CQ506LTGI or 9FGV1004CQ506LTGI, provided the frequency settings and pinout compatibility are verified. Cross-family substitutes require careful evaluation of jitter performance and output drive strength.
