9FGV1002CQ505LTGI

Overview

The 9FGV1002CQ505LTGI is a programmable PhiClock™ clock generator manufactured by Renesas Electronics. It provides four spread-spectrum output pairs and two LVCMOS reference outputs, supporting PCIe Gen1 through Gen7 compliance with typical phase jitter of 276fs RMS at 156.25MHz (12kHz–20MHz). The device accepts input frequencies from 1MHz to 325MHz via crystal, LVCMOS, LVDS, or HCSL sources. Output frequencies range up to 325MHz for LVDS/LP-HCSL and 200MHz for LVCMOS. It operates on core voltages of 1.8V or 3.3V and individual output supply voltages of 1.8V, 2.5V, or 3.3V. The component is housed in a 4x4mm 24-VFQFPN package.

Feature Summary

• PCIe Gen1–7 compliant with common clock jitter less than 41fs RMS
• Four programmable output pairs plus two LVCMOS REF outputs
• Supports integer, fractional, and spread-spectrum frequency generation
• Hardware selection via select pins or software selection via I²C

Applications

• PCI Express timing solutions
• Ethernet clock generation
• Automotive timing applications

Procurement Notes

Verify the specific suffix LTGI against the official datasheet to confirm the package type and moisture sensitivity level. Confirm RoHS compliance status directly with the manufacturer documentation. Check current availability as lead times may vary significantly due to production constraints.

Selection Notes

Select this model when PCIe Gen1–7 low jitter performance is required alongside multiple differential outputs. Ensure the design supports the 1.8V or 3.3V core voltage options. Verify that the 4x4mm VFQFPN package fits the PCB layout constraints and thermal requirements.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. The 9FGV1002 series is designed for high-performance timing applications requiring flexible output configurations and strict jitter specifications for modern interface standards.

Replacement Considerations

Consult the official datasheet for direct pin-compatible substitutes within the 9FGV1002 series. Verify electrical parameters and package dimensions before substituting with other clock generator models.
