9FGV1004B121NBGI

Overview

The Renesas 9FGV1004B121NBGI is a programmable PhiClock generator from the 9FGV1004 family, housed in a 24-VFQFPN package. It provides four differential output pairs supporting LP-HCSL and LVDS signaling standards. The device operates on a core voltage of 1.8 V to 3.3 V with individual I/O supply options. It supports integer frequencies up to 325 MHz and accepts spread spectrum inputs. Key electrical parameters include a maximum input frequency of 240 MHz, a typical phase jitter of 267 fs RMS at 156.25 MHz (12 kHz–20 MHz), and a power consumption of approximately 125 mW.

Feature Summary

• PCIe Gen1 through Gen4 compliant with low phase jitter performance
• Four programmable output pairs plus two LVCMOS reference outputs
• Supports LP-HCSL, LVDS, and LVCMOS I/O standards with flexible supply voltages
• Hardware or I²C configuration selection with four unique addresses

Applications

• PCI Express compliant systems
• High-speed data communication interfaces
• Server and storage backplanes
• Networking equipment requiring precise clock generation

Procurement Notes

Verify availability status as specific suffixes may indicate end-of-life or limited distribution channels. Confirm package type matches design requirements, as the 9FGV1004 series includes both VFQFPN and LGA variants. Ensure I²C address settings align with system constraints for multi-device configurations.

Selection Notes

Select this component when PCIe Gen1-Gen4 compliance and low jitter are required. Choose based on output signaling needs; this model supports LP-HCSL and LVDS. Verify that the 24-pin VFQFPN package fits the PCB layout. Consider the 1.8 V to 3.3 V operating range for power budgeting.

Part Context

This part belongs to the Renesas PhiClock programmable clock generator family. It shares architectural features with other 9FGV1004 variants but differs in factory-configured output frequencies and packaging. The 'NBG' suffix typically denotes the 24-VFQFPN package format.

Replacement Considerations

Direct replacements within the same family include other 9FGV1004 variants with compatible pinouts. Verify that substitute parts support the required output frequencies and signaling standards. Cross-reference datasheets for electrical parameter compatibility.
