9FGV1004BQ534LTGI

Overview

The 9FGV1004BQ534LTGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for low phase-noise and low-power applications. It supports PCIe Gen1–4 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, accepting input frequencies up to 240MHz and generating outputs up to 325MHz. It operates within a supply voltage range of 1.71V to 3.465V and is housed in a compact VFQFPN-24 package.

Feature Summary

• PCIe Gen1–4 compliant with 267fs RMS typical phase jitter at 156.25MHz
• Four programmable differential output pairs supporting LP-HCSL and LVDS standards
• Input frequency range up to 240MHz with maximum output frequency of 325MHz
• Factory-configurable via I²C or hardware select pins with four unique addresses

Applications

• PCI Express (Gen1–Gen4) system clocking
• High-speed data communication interfaces
• Server and storage controller timing solutions

Procurement Notes

The 9FGV1004BQ534LTGI is listed as obsolete by the manufacturer. Verification of availability should focus on secondary market distributors or surplus suppliers, as primary channel stock is not guaranteed. Confirm lot dates and authenticity when sourcing from non-primary vendors due to end-of-life status.

Selection Notes

Select this component for designs requiring precise PCIe-compliant clock generation with low jitter performance. Ensure the design accommodates the VFQFPN-24 package dimensions and thermal requirements. Verify that the required output frequencies fall within the 1MHz–325MHz range and that the power supply constraints align with the 1.71V–3.465V operating window.

Part Context

This part belongs to the 9FGV1004 series of programmable PhiClock generators. It shares architectural similarities with other members like the 9FGV1004BQ500LTGI but differs in factory-programmed configuration parameters. The series is characterized by its flexibility in generating multiple integer and fractional/spread-spectrum frequencies from a single crystal input.

Replacement Considerations

Direct replacement parts are limited due to the specific factory programming. Consider the 9FGV1004BQ500LTGI if the pinout and electrical specifications match the design requirements, though functional equivalence depends on verifying the programmed output frequencies. Other PhiClock family members may serve as alternatives if reprogramming capabilities are available.
