9FGV1002B111NBGI

Clock Generators, PLLs, Frequency Synthesizers Overview

The Renesas 9FGV1002B111NBGI is a PhiClock™ programmable clock generator designed for Ethernet and PCI Express applications. It features an integrated PLL to generate precise clock signals from a single reference input. The device supports multiple output voltage levels, including 1.71V–1.89V, 2.375V–2.625V, and 3.135V–3.465V. It offers flexible configuration via hardware select pins or I²C software control, providing four spread-spectrum copies of a single output frequency and two copies of the crystal reference input. The component operates within a temperature range of -40°C to 85°C and holds AEC-Q100 automotive qualification.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix 'B111' against the official 9FGV1002C datasheet addendum to confirm the exact output frequencies and package variant. Confirm availability status as supply constraints may affect order fulfillment. Ensure the selected package type matches the design requirements for the target application board.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when spread-spectrum clocking is required for PCIe or Ethernet links to reduce EMI. Verify that the required output voltage levels (1.8V, 2.5V, or 3.3V domains) are supported by the power supply rails. Check if I²C configurability is needed for dynamic frequency changes or if fixed hardware configuration suffices. Ensure the input reference frequency matches the available crystal oscillator.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the Renesas PhiClock™ 9FGV1002 series, which includes variants like 9FGV1001, 9FGV1002, and 9FGV1004. The 'C' in the base model number typically denotes the specific generation or feature set covered in the main datasheet. Suffixes such as 'NBG2' indicate the VFQFPN package type, while other letters define factory programming and temperature grades.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements must be from the 9FGV1002 series with compatible pinouts and electrical characteristics. Verify that substitute parts support the same output voltage ranges and signal types (e.g., LVPECL, LVDS). Ensure the replacement maintains AEC-Q100 qualification if used in automotive applications.
