9FGV1001B004NBGI8

Overview

The 9FGV1001B004NBGI8 is a programmable clock generator from Renesas' PhiClock family, designed for PCIe Gen1 through Gen5 applications. It features four non-spread-spectrum output copies of a single frequency and two crystal reference input copies. The device operates with a 1.8V core voltage and supports LP-HCSL differential signaling. It offers hardware selection via select pins or software configuration through I²C, allowing flexible deployment in high-speed digital systems requiring precise timing.

Feature Summary

• PCIe Gen1 to Gen5 compliant with typical RMS phase jitter of 0.261 ps
• Four LP-HCSL outputs and two LVCMOS reference outputs
• Configurable via hardware strapping pins or I²C interface
• Available in 24-lead VFQFPN (4.0 x 4.0 mm) package

Applications

• PCI Express Gen1, Gen2, Gen3, Gen4, and Gen5 system clocks
• High-performance computing platforms
• Data center infrastructure equipment

Procurement Notes

Verify the specific suffix NBGI8 against the manufacturer's current datasheet to confirm packaging details and lead-free status. Confirm that the factory-configured parameters match the design requirements, as this is a custom part number. Check for updated product change notifications regarding assembly locations or material changes.

Selection Notes

Select this component when low jitter performance is critical for PCIe Gen5 signals. Ensure the board layout accommodates the 24-pin VFQFPN package dimensions. Verify that the I²C address configuration does not conflict with other devices on the bus if multiple clock generators are used in the system.

Part Context

This part belongs to the 9FGV1001 series, which provides fixed-frequency outputs configured at the factory. Unlike fully programmable variants, these devices use OTP memory to store the clock synthesis settings, reducing system complexity by eliminating the need for external programming during operation.

Replacement Considerations

Direct replacements within the same family include other 9FGV1001 variants with different output frequencies or packaging options. Cross-family substitution with 9FGV1004 requires verification of output types and pin compatibility.
