9FGV1006BQ538LTGI

Overview

The Renesas 9FGV1006BQ538LTGI is a programmable PhiClock generator designed for high-speed serial interface timing. It supports PCIe Gen1 through Gen7 compliance with typical phase jitter of 276fs RMS at 156.25MHz (12kHz–20MHz). The device features four programmable output pairs and two LVCMOS reference outputs, supporting LP-HCSL, LVDS, and LVCMOS signaling standards. Operating frequencies range from 1MHz to 325MHz for differential outputs and up to 200MHz for LVCMOS. It utilizes a 1.8V core voltage with individual 1.8V, 2.5V, or 3.3V VDDO options per output pair.

Feature Summary

• PCIe Gen1–7 compliant with low jitter performance
• Four programmable output pairs plus two LVCMOS REF outputs
• Supports integer, fractional, and spread-spectrum frequency modes
• Configurable via hardware select pins or I²C software control

Applications

• PCI Express system clock generation
• High-speed data communication interfaces
• Server and storage backplane timing

Procurement Notes

Verify the specific suffix BQ538LTGI against official Renesas documentation to confirm factory configuration parameters, including exact output frequencies and I²C addresses. Ensure compatibility with required I/O voltage levels (1.8V/2.5V/3.3V) and package type (24-VFQFPN or 24-LGA) before procurement.

Selection Notes

Select this component when PCIe Gen7 jitter specifications are required. Compare with the 9FGV1002 if spread-spectrum functionality is needed, as the 9FGV1006 series typically offers fixed or specific programmable configurations depending on the suffix. Verify that the 156.25MHz input requirement aligns with the system crystal oscillator availability.

Part Context

This part belongs to the Renesas PhiClock™ programmable clock generator family, which includes models like the 9FGV1001, 9FGV1002, and 9FGV1004. These devices are engineered to provide precise clocking solutions for high-speed digital interfaces, particularly focusing on reducing jitter in PCI Express applications.
