9FGV1002BQ515LTGI8

Overview

The 9FGV1002BQ515LTGI8 is a programmable PhiClock™ clock generator from Renesas Electronics, designed for PCIe Gen1–7 applications. It features four spread-spectrum output pairs and two LVCMOS reference outputs, supporting frequencies up to 325MHz (LVDS/LP-HCSL) or 200MHz (LVCMOS). The device operates with core voltages of 1.8V or 3.3V and individual output supply options of 1.8V, 2.5V, or 3.3V. It includes an integrated 50MHz crystal option and supports I²C configuration with four unique addresses. The component is housed in a 4x4mm 24-VFQFPN package and is rated for automotive use under AEC-Q100 standards.

Feature Summary

• PCIe Gen1–7 compliant with typical phase jitter of 276fs RMS at 156.25MHz
• Four programmable differential output pairs plus two LVCMOS REF outputs
• Supports HCSL, LVDS, LVCMOS, LP-HCSL, AC-coupled LVPECL, and CML signaling
• Factory-configurable with hardware select pins or I²C software selection

Applications

• PCI Express (PCIe) timing solutions for Gen1 through Gen7
• Automotive infotainment and connectivity systems requiring AEC-Q100 compliance
• Ethernet interface clock generation
• High-speed data acquisition systems

Procurement Notes

Verify the specific suffix 'BQ515LTGI8' against official Renesas documentation to confirm factory configuration details, as suffixes define internal programming and packaging. Confirm availability status directly with distributors, as lead times may vary due to supply constraints. Ensure the ordering part number matches the required package type and moisture sensitivity level specifications.

Selection Notes

Select this component when designing for PCIe Gen1–7 environments requiring low jitter performance below 41fs RMS. Choose this model if the design requires four differential output pairs with flexible I/O standards including LP-HCSL and LVDS. Verify that the system can accommodate the 1.8V to 3.3V core voltage range and individual output supply requirements. Consider the integrated 50MHz crystal option if external oscillators are undesirable.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. The 9FGV1002 series is specifically optimized for high-speed serial link applications like PCIe and Ethernet. It offers flexibility through multiple output configurations and support for spread-spectrum frequency modulation to reduce EMI. The device integrates PLL functionality and supports both hardware and software configuration methods.

Replacement Considerations

Direct replacements within the same family include other 9FGV1002 variants with different suffixes for distinct factory configurations or packaging options. Cross-model comparisons should consider the 9FGV1005 or 9FGV1006 series if output count or specific frequency ranges differ. Always verify pin compatibility and electrical parameters before substitution.
