9FGV1004B208NBGI

Overview

The 9FGV1004B208NBGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for high-performance timing applications. It features four differential output pairs supporting LP-HCSL and LVDS signaling standards, with individual 1.8V to 3.3V VDDO control for each pair. The device operates within a supply voltage range of 1.71V to 3.465V and supports integer frequencies up to 325MHz. It utilizes a 24-pin VFQFPN package (4x4mm) and includes an integrated crystal option. Key specifications include a typical phase jitter of 267fs RMS at 156.25MHz and compliance with PCIe Gen1 through Gen4 standards.

Feature Summary

• Four programmable differential output pairs with selectable LP-HCSL or LVDS signaling
• Individual 1.8V to 3.3V core and I/O voltage support for flexible interface compatibility
• Hardware or I²C configuration selection with four unique I²C addresses
• PCIe Gen1–4 compliant with typical 267fs RMS phase jitter at 156.25MHz

Applications

• PCI Express (Gen1-Gen4) system clock generation
• High-speed data communication interfaces requiring low jitter
• Server and storage subsystems needing multiple synchronized clock domains
• Industrial equipment requiring precise timing synchronization

Procurement Notes

Verify the specific suffix 'NBGI' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote package type or temperature range. Confirm availability status, as some variants in this series may be discontinued or subject to long lead times. Ensure the selected part matches the required output frequency and voltage levels for the target application design.

Selection Notes

Select this component when designing systems requiring four independent differential clock outputs with mixed voltage domains. The 9FGV1004B208NBGI is suitable for applications needing hardware-configurable default settings via select pins or software-controlled I²C access. Consider the 24-VFQFPN package constraints for PCB layout and thermal management. Verify that the input crystal frequency and desired output multiples align with the device's internal PLL capabilities.

Part Context

This part belongs to the Renesas PhiClock 9FGV1004 series, which offers programmable clock generation solutions for high-speed digital interfaces. The series is characterized by its flexibility in output formats and low jitter performance, making it a common choice for modern computing and networking platforms. The NBGI suffix typically indicates a specific tape-and-reel or tray packaging variant for surface-mount assembly.

Replacement Considerations

Direct replacements within the same family include other 9FGV1004 variants with different output configurations or voltage ranges. Cross-family alternatives from other manufacturers should be evaluated based on pin compatibility, jitter specifications, and supported output standards. Always verify that any substitute part meets the specific PCIe compliance requirements if used in such applications.
