9FGV1004B000NBGI

Overview

The 9FGV1004B000NBGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for high-performance timing applications. It features four differential output pairs capable of generating frequencies up to 325 MHz using LP-HCSL or LVDS signaling standards. The device supports integer and fractional PLL synthesis with spread-spectrum capabilities to reduce EMI. It operates on a single supply voltage ranging from 1.71 V to 3.465 V and includes two LVCMOS reference outputs derived from the crystal input. The component is housed in a compact 24-pin VFQFPN package.

Feature Summary

• Four programmable differential output pairs supporting LP-HCSL and LVDS standards
• Maximum output frequency of 325 MHz with typical phase jitter of 267 fs RMS (156.25 MHz, 12 kHz–20 MHz)
• Supports PCIe Gen1 through Gen4 compliance requirements
• Configurable via hardware select pins or I²C interface with four unique addresses

Applications

• PCI Express (PCIe) Gen1-Gen4 system timing
• Ethernet network infrastructure equipment
• High-speed data acquisition systems
• Industrial control systems requiring precise clock distribution

Procurement Notes

Verify the specific suffix 'B000NBGI' against official Renesas documentation to confirm factory configuration parameters. Check current lifecycle status as programmable variants may have limited availability or obsolescence notices. Ensure compatibility with existing PCB footprints for the 24-VFQFPN package before procurement.

Selection Notes

Select this component when multiple differential clock outputs are required for PCIe or Ethernet interfaces. Verify that the required output frequencies fall within the 1 MHz to 325 MHz range. Confirm that the power supply constraints align with the 1.71 V to 3.465 V operating window. Consider the 24-pin VFQFPN package size if space is limited.

Part Context

This part belongs to the 9FGV1004 series, which offers flexible clock generation solutions. Unlike fixed-frequency oscillators, this device allows customization of output frequencies and formats during manufacturing or via software configuration. It serves as a central timing hub for complex digital systems requiring low-jitter clock signals.

Replacement Considerations

Direct replacements include other members of the 9FGV1004 family such as 9FGV1004C or 9FGV1004D, provided pinout and electrical specifications match. Cross-family alternatives from other manufacturers require careful evaluation of jitter performance and output drive strength.
