9FGV1001B110NBGI

Overview

The 9FGV1001B110NBGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for PCIe Gen1 through Gen5 applications. It features four non-spread-spectrum output copies and two crystal reference input copies. The device supports hardware selection via select pins or software configuration through I²C. It operates with a core voltage of 1.8V and delivers LP-HCSL outputs. Typical RMS phase jitter is specified at 0.261 ps. The component is housed in a 4.0 x 4.0 mm 24-lead VFQFPN package.

Feature Summary

• PCIe Gen1 to Gen5 compliant timing solution
• Four non-spread-spectrum output copies plus two reference inputs
• Hardware (select pins) or software (I²C) configuration options
• Low typical RMS phase jitter of 0.261 ps

Applications

• PCI Express (PCIe) Gen1 systems
• PCI Express (PCIe) Gen2 systems
• PCI Express (PCIe) Gen3 systems
• PCI Express (PCIe) Gen4 systems
• PCI Express (PCIe) Gen5 systems

Procurement Notes

Verify the specific frequency configuration associated with the B110 suffix against official datasheets, as this identifier denotes factory-programmed parameters. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure compatibility with the target system's I²C addressing requirements, noting that four unique addresses are supported within the family.

Selection Notes

Select this component when designing for PCIe generations requiring low jitter performance without spread spectrum modulation. Verify that the required output frequencies fall within the supported range of approximately 161 MHz to 322 MHz. Ensure the design accommodates the 1.8V core supply and LP-HCSL output standards. Consider the 24-lead VFQFPN package dimensions for PCB layout constraints.

Part Context

This part belongs to the 9FGV1001 series, which provides fixed-frequency outputs programmed at the factory. Unlike the C-series variants that allow field reconfiguration via I²C, the B-series represents a specific factory-configured instance. It shares the same physical package and electrical characteristics as other members of the 9FGV1001 family.

Replacement Considerations

Direct functional replacements include other 9FGV1001 series parts with matching output frequencies. Verify pinout compatibility with the 24-VFQFPN package. Cross-reference with 9FGV1002 or 9FGV1004 series only if spread spectrum or different output counts are acceptable.
