9FGV1004B219NBGI8

Overview

The 9FGV1004B219NBGI8 is a programmable PhiClock generator from Renesas Electronics, designed for high-speed digital interfaces. It supports PCIe Gen1 through Gen4 compliance with typical phase jitter of 267fs RMS at 156.25MHz (12kHz–20MHz). The device provides four programmable output pairs plus two LVCMOS reference outputs, supporting LP-HCSL, LVDS, and LVCMOS signaling standards. Operating voltages are 1.8V or 3.3V for core and I/O supplies. It features integer and fractional/spread-spectrum output capabilities within frequency ranges up to 325MHz.

Feature Summary

• PCIe Gen1-4 compliant with low phase jitter performance
• Four programmable differential output pairs (LP-HCSL/LVDS) and two LVCMOS references
• Supports 1.8V and 3.3V supply voltages with individual VDDO control
• Factory-configurable via OTP with hardware select pins or I2C software selection

Applications

• PCI Express timing solutions for servers and storage
• High-speed data communication systems requiring precise clocking
• Industrial equipment with strict EMI requirements using spread spectrum

Procurement Notes

Verify the specific suffix B219 against official Renesas documentation to confirm factory configuration parameters. Check current production status as programmable devices may have limited availability or long lead times depending on the specific OTP programming request. Ensure compatibility with existing I2C addressing schemes if multiple components are used.

Selection Notes

Select this component when PCIe Gen1-4 jitter specifications are critical. Compare output drive strength requirements between LP-HCSL and LVDS based on trace impedance. Verify that the required output frequencies fall within the supported 1MHz–325MHz range for integer modes or 1MHz–200MHz for LVCMOS. Confirm package availability in 24-VFQFPN or 24-LGA formats.

Part Context

Part of the PhiClock family of programmable clock generators. Shares common architecture with models like 9FGV1001 and 9FGV1002 but offers distinct output configurations and jitter performance optimized for PCI Express applications. Differentiated by its specific factory-programmed frequency set defined by the B219 suffix.

Replacement Considerations

Direct pin-to-pin replacements within the same package require identical OTP configurations. Generic substitutes must match jitter specs and output standards. Verify I2C address compatibility if replacing in multi-device systems.
