9FGV1002BQ508LTGI8

Overview

The 9FGV1002BQ508LTGI8 is a programmable PhiClock generator from Renesas Electronics, designed for PCIe Gen1–7 compliance. It features four spread-spectrum output pairs and two LVCMOS reference outputs. The device supports LP-HCSL, LVDS, and LVCMOS signaling standards with output frequencies ranging from 1MHz to 325MHz. It operates on core voltages of 1.8V or 3.3V, with individual VDDO options of 1.8V, 2.5V, or 3.3V per output pair. Typical phase jitter at 156.25MHz is 276fs RMS (12kHz–20MHz), meeting stringent PCIe Gen7 common clock requirements.

Feature Summary

• PCIe Gen1–7 compliant with low jitter performance suitable for high-speed serial links
• Four programmable differential output pairs plus two LVCMOS reference outputs
• Supports integer, fractional, and spread-spectrum frequency generation modes
• Configurable via hardware select pins or I²C interface with four unique addresses

Applications

• PCI Express (Gen1 through Gen7) system clocking
• High-performance computing and server infrastructure
• Data center interconnects requiring precise timing synchronization

Procurement Notes

Verify the specific suffix 'BQ508LTGI8' against official Renesas documentation to confirm factory configuration details, as suffixes define programming parameters and package type. Ensure compatibility with required I/O voltage levels and input crystal frequencies before procurement.

Selection Notes

Select this component when PCIe Gen7 jitter specifications are critical. Confirm that the available output swing standards (LP-HCSL/LVDS) match the receiver inputs. Verify that the 1MHz–325MHz frequency range covers all required system clocks and that the 4mm x 4mm package fits the PCB layout constraints.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. The 9FGV1002 series is optimized for automotive and industrial applications requiring AEC-Q100 qualification. It serves as a central timing solution for multi-lane high-speed interfaces, replacing multiple fixed-frequency oscillators.

Replacement Considerations

Direct replacements within the same family include other 9FGV1002 variants with different suffixes for distinct factory configurations. Cross-family alternatives like the 9FGV1004 offer more outputs but may differ in pinout or power consumption.
