9FGV1004B120NBGI8

Overview

The Renesas 9FGV1004B120NBGI8 is a programmable PhiClock generator in the 9FGV1004 family, designed for PCIe Gen1–Gen4 compliance. It features four differential output pairs supporting LP-HCSL and LVDS signaling standards. The device operates with a core voltage of 1.8V or 3.3V and supports individual VDDO levels from 1.8V to 3.3V per output pair. It provides two integer-related frequencies, one fractional or spread-spectrum frequency, and two crystal reference copies. Configuration is selectable via hardware pins or I²C software control.

Feature Summary

• PCIe Gen1–Gen4 compliant with typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz)
• Four programmable differential output pairs plus two LVCMOS reference outputs
• Supports LP-HCSL and LVDS output signaling standards
• Configurable via hardware select pins or I²C interface

Applications

• PCI Express timing solutions
• High-speed data communication systems
• Server and storage infrastructure clocking

Part Context

This component belongs to the Renesas PhiClock™ programmable clock generator family. The 9FGV1004 series offers flexible configuration options for generating multiple clock frequencies from a single input source, suitable for complex system timing requirements.

Replacement Considerations

Verify pinout compatibility and electrical specifications against current inventory. Check for updated package variants or lead-free status changes in newer revisions.
