9FGV1004B120NBGI

Overview

The 9FGV1004B120NBGI is a programmable PhiClock generator from Renesas Electronics, designed for PCIe Gen1 through Gen4 applications. It features four differential output pairs supporting LP-HCSL and LVDS signaling standards, with individual 1.8V to 3.3V VDDO control for each pair. The device accepts integer inputs ranging from 1MHz to 325MHz and fractional or spread-spectrum outputs. It includes two LVCMOS reference outputs and supports hardware selection via select pins or software configuration through I²C. The component operates within a -40°C to 85°C temperature range and is available in 4x4 mm 24-VFQFPN and 24-LGA packages.

Feature Summary

• PCIe Gen1–4 compliant with typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz)
• Four programmable output pairs plus two LVCMOS reference outputs
• Supports LP-HCSL and LVDS output signaling with individual 1.8V to 3.3V core VDDO
• Configurable via hardware select pins or I²C interface with four unique addresses

Applications

• PCI Express Gen1, Gen2, Gen3, and Gen4 timing solutions
• High-speed data acquisition systems requiring low phase noise
• Industrial equipment needing programmable clock generation

Procurement Notes

Verify the specific suffix 'B120' against official Renesas documentation to confirm factory-configured frequency parameters. Ensure package type matches design requirements, as the family supports both VFQFPN and LGA options. Confirm I²C address settings if multiple components are used on the same bus. Check for any recent Product Change Notifications regarding assembly locations or material compliance updates.

Selection Notes

Select this component when PCIe Gen1–4 compliance is required with low power consumption. Choose based on output voltage needs, as each pair supports independent 1.8V to 3.3V levels. Consider the 4x4 mm package size for space-constrained designs. Verify that the input frequency range (1MHz–325MHz) aligns with system crystal or oscillator availability. Use Timing Commander™ software for configuration validation.
