9FGV1002CQ515LTGI8

Overview

The Renesas 9FGV1002CQ515LTGI8 is a programmable PhiClock™ 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 of 1.8V, 2.5V, or 3.3V. It includes an integrated crystal option and supports I²C configuration with four unique addresses.

Feature Summary

• PCIe Gen1–7 compliant with typical phase jitter of 276fs RMS at 156.25MHz (12kHz–20MHz)
• Four programmable output pairs plus two LVCMOS REF outputs
• Supports HCSL, LVDS, LVCMOS, LP-HCSL, AC-coupled LVPECL, and CML standards
• Factory configured with selectable hardware or I²C configuration modes

Applications

• PCI Express (PCIe) Gen1 through Gen7 systems
• Ethernet clock generation
• High-speed digital interface timing solutions

Procurement Notes

Verify the specific suffix LTGI8 corresponds to the tape-and-reel packaging format. Confirm the factory-programmed frequency configuration matches the system requirements, as this is a pre-configured device rather than a blank programmable unit. Check AEC-Q100 automotive qualification status if applicable to the target application environment.

Selection Notes

Select this component when PCIe Gen1–7 common clock jitter specifications are required. Ensure the design accommodates the 4x4mm 24-VFQFPN package dimensions. Verify that the available output voltage levels (1.8V/3.3V core, 1.8V/2.5V/3.3V output) align with the downstream receiver logic requirements.

Part Context

This part belongs to the Renesas PhiClock™ family of programmable clock generators. It is specifically optimized for high-performance computing and communication interfaces requiring low-jitter clock distribution. The 9FGV1002 series provides flexibility in output signaling standards while maintaining compliance with stringent PCIe timing standards.

Replacement Considerations

Direct replacements within the same family include other 9FGV1002 variants with different factory configurations or package types. Cross-family alternatives may include the 9FGV1004 or 9FGV1005 series, though output counts and specific jitter performance must be verified against the original design constraints.
