9FGV1004BQ534LTGI8

Overview

The 9FGV1004BQ534LTGI8 is a programmable PhiClock generator from Renesas Electronics, designed for low phase-noise and low-power applications. It supports PCIe Gen1 through Gen4 compliance with typical RMS phase jitter of 267fs at 156.25MHz (12kHz–20MHz). The device features four programmable output pairs plus two LVCMOS reference outputs, supporting LP-HCSL and LVDS signaling standards. Operating within a supply voltage range of 1.71V to 3.465V, it delivers integer outputs up to 325MHz and fractional/spread-spectrum outputs up to 200MHz. Packaged in a compact 4x4mm 24-VFQFPN format, it integrates an optional 50MHz crystal.

Feature Summary

• PCIe Gen1–4 compliant with 267fs RMS typical phase jitter at 156.25MHz
• Four programmable output pairs (LP-HCSL/LVDS) and two LVCMOS reference outputs
• Supports integer frequencies up to 325MHz and fractional/spread-spectrum up to 200MHz
• Factory-configurable via OTP with hardware select pins or I²C software control

Applications

• PCI Express (Gen1–Gen4) clock generation
• Intel CPU server systems
• SATA interface timing
• General-purpose system control clocks

Procurement Notes

Verify the specific suffix 'BQ534LTGI8' against official Renesas documentation to confirm factory configuration parameters, as suffixes define internal programming. Check current lifecycle status, as some variants may be obsolete or have limited availability. Confirm moisture sensitivity level (MSL 3) and reflow soldering profiles prior to assembly.

Selection Notes

Select this component when PCIe Gen1–4 compliance and low jitter are required. Ensure the design supports the 1.71V–3.465V supply range. Verify that the 24-VFQFPN package fits the PCB footprint. Use Timing Commander™ software for configuration if I²C control is preferred over hardware pin selection.

Part Context

This part belongs to the Renesas PhiClock 9FGV1004 family, which includes variants like 9FGV1004BQ500LTGI and 9FGV1004CQ501LTGI8. These devices share common architectural features such as the 24-pin VFQFPN/LGA packages and support for multiple I/O standards including LP-HCSL, LVDS, and LVCMOS.

Replacement Considerations

Direct substitutes within the same family include 9FGV1004BQ500LTGI and 9FGV1004CQ501LTGI8. Verify that the replacement part's factory configuration matches the original design requirements, as different suffixes indicate distinct pre-programmed settings.
