9FGV1004B114NBGI

Overview

The 9FGV1004B114NBGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for high-performance timing applications. It features four differential outputs supporting LP-HCSL and LVDS signaling standards. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports output frequencies up to 325 MHz. It utilizes a 24-pin VFQFPN package with dimensions of 4.0 x 4.0 mm. The component exhibits a typical RMS phase jitter of 267 fs at 156.25 MHz (12 kHz–20 MHz bandwidth) and includes spread-spectrum capability. It is configured via hardware select pins or I²C interface.

Feature Summary

• Four differential output pairs with configurable LP-HCSL or LVDS signaling
• Supports PCIe Gen1 through Gen4 compliance with low jitter performance
• Integrated spread-spectrum clock generation capability
• Flexible configuration via two hardware select pins or I²C software control

Applications

• PCI Express (PCIe) compliant systems
• Intel CPU server platforms
• SATA interface clocking
• High-speed data communication equipment

Procurement Notes

Verify the specific suffix NBGI against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution channels may list obsolete or end-of-life variants. Ensure compatibility with existing board layouts regarding the 24-VFQFPN footprint and thermal requirements.

Selection Notes

Select this component when four independent differential clock outputs are required for PCIe or similar high-speed serial interfaces. Verify that the input crystal frequency matches the design requirements, as the device accepts integer and fractional multiples. Ensure the system power budget accommodates the core voltage range of 1.8 V to 3.3 V and output driver currents.

Part Context

This part belongs to the 9FGV1004 series, which provides flexible clock generation solutions for multi-standard interfaces. The PhiClock family is characterized by its ability to generate multiple related frequencies from a single reference, reducing component count in complex digital systems requiring synchronized timing domains.

Replacement Considerations

Direct replacements include other 9FGV1004 variants with different output frequencies or packaging options, such as 9FGV1004BQ500LTGI. Cross-model substitution requires verification of pin compatibility and electrical parameters against the original design specifications.
