9FGV1004B212NBGI

Overview

The Renesas 9FGV1004B212NBGI is a programmable PhiClock generator in the 9FGV1004 family, designed for PCIe Gen1–4 compliance. It features four differential outputs supporting LP-HCSL and LVDS signaling standards. The device operates with a core voltage of 1.8V to 3.3V and supports output frequencies ranging from 1MHz to 325MHz. It includes two integer-related frequency copies, one fractional or spread-spectrum copy, and two crystal reference copies. Configuration is selectable via hardware pins or I²C software control.

Feature Summary

• PCIe Gen1–4 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 provides flexible clock generation capabilities for high-speed digital interfaces. It is available in compact packages such as VFQFPN-24 and LGA-24, facilitating integration into space-constrained designs requiring precise clock distribution.

Replacement Considerations

Direct replacements within the same family include variants like 9FGV1004BQ500LTGI and 9FGV1004CQ501LTGI8. Selection depends on specific output frequency requirements, package type (VFQFPN vs. LGA), and configuration method (factory programmed vs. I²C). Verify that the substitute part supports the required output signaling standards and jitter performance for the target application.
