9FGV1002CQ505LTGI8

Overview

The Renesas 9FGV1002CQ505LTGI8 is a PhiClock™ programmable clock generator 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) and 200MHz (LVCMOS). The device operates with core voltages of 1.8V or 3.3V and individual output supply options. It includes an integrated 50MHz crystal option and supports hardware or I²C configuration via select pins or software commands.

Feature Summary

• PCIe Gen1–7 compliant with common clock jitter < 41fs RMS
• Four programmable output pairs plus two LVCMOS REF outputs
• Supports HCSL, LVDS, LVCMOS, LP-HCSL, AC-coupled LVPECL, and CML standards
• Hardware or I²C configuration with four unique I²C addresses

Applications

• PCI Express (PCIe) Gen1 through Gen7 systems
• Ethernet infrastructure requiring precise timing
• High-performance computing platforms

Procurement Notes

Verify the specific suffix LTGI8 against the official datasheet to confirm package type and configuration. Confirm availability status as inventory levels fluctuate. Ensure compatibility with required I/O voltage standards before procurement.

Selection Notes

Select this component when PCIe Gen7 low jitter requirements are critical. Choose based on required output signaling standards (LP-HCSL vs LVDS). Verify that the 1:6 input-to-output ratio meets system topology needs. Check if the integrated crystal option simplifies board design compared to external crystals.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. It is specifically engineered for high-speed serial interface timing, offering flexibility in frequency generation and output formatting for complex multi-lane architectures.

Replacement Considerations

Direct substitutes within the same family include 9FGV1002C000NBG2 and 9FGV1002CQ501LTGI8. Verify pinout and configuration settings match exactly when swapping between variants.
