9FGV1004B211NBGI8

Overview

The Renesas 9FGV1004B211NBGI8 is a programmable PhiClock generator designed for high-speed digital interfaces. It supports PCIe Gen1 through Gen4 compliance with typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz). The device provides four programmable differential output pairs and two LVCMOS reference outputs, supporting LP-HCSL, LVDS, and LVCMOS signaling standards. Operating frequencies range from 1MHz to 325MHz for integer outputs. It features I²C configuration with four unique addresses and hardware select pins.

Feature Summary

• PCIe Gen1-4 compliant with low phase noise performance
• Four programmable differential output pairs plus two LVCMOS ref outputs
• Supports LP-HCSL, LVDS, and LVCMOS I/O standards
• I²C configurable with four unique addresses

Applications

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

Procurement Notes

Verify the specific suffix B211 against official Renesas documentation to confirm factory-configured frequency parameters. Ensure the NBGI8 package designation matches the required 24-VFQFPN or LGA form factor for the target PCB layout. Confirm RoHS compliance status via the latest datasheet revision.

Selection Notes

Select this component when PCIe Gen1-4 jitter specifications are critical. Verify that the required output frequencies fall within the 1MHz to 325MHz integer range. Check if LP-HCSL or LVDS signaling is preferred over LVCMOS for the specific application environment. Ensure I²C address conflicts are resolved if multiple devices are used on the same bus.

Part Context

This part belongs to the Renesas PhiClock family of programmable clock generators. It is an evolution of earlier IDT designs acquired by Renesas. The 9FGV1004 series is specifically optimized for timing applications requiring low jitter and flexible output configurations for modern interface standards.

Replacement Considerations

Direct replacements include other 9FGV1004 variants with different suffixes for adjusted frequencies or packages. Cross-reference with 9FGV1004C series for updated packaging options. Verify pin compatibility before substituting with older 9FGV1004 models.
