9FGV1004B214NBGI8

Overview

The 9FGV1004B214NBGI8 is a programmable PhiClock generator manufactured by Renesas Electronics. It provides four differential output pairs supporting LP-HCSL and LVDS signaling standards, along with two LVCMOS reference outputs. The device accepts integer or fractional/spread-spectrum inputs within the 1 MHz to 325 MHz range for integer outputs. It features low phase noise performance, typically 267 fs RMS jitter at 156.25 MHz (12 kHz–20 MHz bandwidth). Power consumption is approximately 125 mW, operating on 1.8 V or 3.3 V supplies. The component is housed in a 4x4 mm 24-VFQFPN package.

Feature Summary

• PCIe Gen1 through Gen4 compliant timing solution
• 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 system clock generation
• High-speed data communication interfaces
• Server and storage subsystem timing

Procurement Notes

Verify the specific suffix NBGI8 against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure the factory-configured frequency parameters match the design requirements, as this is a custom part. Cross-reference the Renesas ordering code with authorized distributors to confirm availability and current revision status.

Selection Notes

Select this component when PCIe Gen1-Gen4 compliance is required with low jitter specifications. Choose between LP-HCSL or LVDS based on the downstream receiver logic compatibility. Verify that the required output frequencies fall within the supported 1 MHz to 325 MHz integer range. Consider the 24-VFQFPN package constraints for PCB layout if space is limited.

Part Context

This part belongs to the Renesas PhiClock family of programmable clock generators. It is designed to replace fixed-frequency oscillators in high-speed digital systems, offering flexibility in frequency synthesis and reduced bill-of-materials complexity by integrating multiple clock domains into a single package.

Replacement Considerations

Direct replacements include other 9FGV1004 variants with different factory configurations but identical pinouts. Check for updated suffixes indicating package changes or revised manufacturing locations. Ensure any substitute maintains the same output voltage levels and jitter performance metrics.
