9FGV1004B208NBGI8

Overview

The Renesas 9FGV1004B208NBGI8 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 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 and up to 200MHz for LVCMOS. Supply voltages are individually configurable for core (1.8V or 3.3V) and I/O (1.8V to 3.3V).

Feature Summary

• PCIe Gen1–4 compliant with 267fs RMS typical phase jitter at 156.25MHz.
• Four programmable differential output pairs plus two LVCMOS reference outputs.
• Supports LP-HCSL, LVDS, and LVCMOS output signaling standards.
• Configurable via hardware select pins or I²C interface.

Applications

• PCI Express (Gen1–Gen4) clock generation.
• High-speed data communication systems.
• Server and storage infrastructure timing.

Procurement Notes

Verify the specific suffix 'B208' against official Renesas documentation to confirm factory configuration details. Confirm package type availability, as the 9FGV1004 family utilizes 24-VFQFPN or 24-LGA packages. Ensure compatibility with Timing Commander™ software for configuration validation.

Selection Notes

Select this component when low jitter performance is critical for PCIe applications. Verify that the required output frequency falls within the 1MHz–325MHz range for differential outputs. Check if LP-HCSL or LVDS signaling matches the downstream receiver requirements. Consider I²C vs. hardware pin selection based on system design flexibility needs.

Part Context

This part belongs to the Renesas PhiClock™ programmable clock generator family. It is an出厂可配置设备 (factory-configured device), meaning the internal PLL settings are fixed at manufacture. Users cannot reprogram the device in-circuit; configuration must be handled during the ordering process using Renesas tools.

Replacement Considerations

Direct replacements within the same family include other 9FGV1004 variants with different output configurations or frequencies. Verify pinout compatibility between VFQFPN and LGA packages if substituting package types. Cross-reference with 9FGV1008 series for higher channel counts if additional outputs are needed.
