9FGV1004B221NBGI8

Overview

The 9FGV1004B221NBGI8 is a programmable clock generator from the Renesas PhiClock family, designed for high-performance timing applications. It features four differential output pairs 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 input frequencies up to 240 MHz with maximum output frequencies reaching 325 MHz. Packaged in a compact 24-VFQFPN format, it integrates spread-spectrum capabilities and offers low jitter performance suitable for PCIe Gen1 through Gen4 compliance.

Feature Summary

• Four programmable differential output pairs with LP-HCSL and LVDS support
• Maximum output frequency of 325 MHz and input frequency up to 240 MHz
• Spread-spectrum generation capability for EMI reduction
• I²C configurable with hardware select pin options

Applications

• PCI Express (Gen1-Gen4) system timing
• Server and storage infrastructure clocks
• High-speed data communication interfaces

Procurement Notes

Verify the specific suffix 'NBGI8' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status as distribution availability varies by region. Ensure I²C address configurations match system requirements before integration.

Selection Notes

Select this component when multiple differential outputs with mixed signaling standards are required. Verify that the 1.71 V to 3.465 V dual-supply architecture aligns with the target board's power rails. Check if the integrated spread-spectrum feature meets electromagnetic interference constraints for the specific application environment.

Part Context

This part belongs to the 9FGV1004 series, which provides flexible clock generation solutions. The 'B' variant typically denotes specific electrical characteristics or package revisions within the PhiClock line. It serves as a drop-in replacement for legacy clock generators requiring multi-standard output support in dense PCB layouts.

Replacement Considerations

Direct substitutes include other 9FGV1004 variants with compatible output counts and signaling types. Verify pin-to-pin compatibility if replacing existing designs. Consider the 9FGV1008 series for additional output channels if future scalability is needed.
