9FGV1004BQ500LTGI

Overview

The 9FGV1004BQ500LTGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for high-performance timing applications. It features four differential outputs supporting LP-HCSL and LVDS signaling standards. The device operates within a supply voltage range of 1.71 V to 3.465 V and supports maximum output frequencies up to 325 MHz with a maximum input frequency of 240 MHz. Packaged in a 24-lead VFQFPN format, it exhibits a typical phase jitter of 27 ps. The component functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Four programmable differential output pairs with LP-HCSL or LVDS signaling options
• Supports integer and fractional/spread-spectrum output configurations via hardware select pins or I²C software control
• Low phase jitter performance with a typical RMS value of 267 fs at 156.25 MHz (12 kHz–20 MHz bandwidth)
• Integrated crystal option support and compatibility with Timing Commander™ configuration software

Applications

• PCI Express Gen1 through Gen4 compliant systems
• Server and storage infrastructure timing
• High-speed data communication interfaces requiring low-jitter clock generation

Procurement Notes

This specific part number is listed as obsolete or discontinued by the manufacturer. Verification of availability should focus on remaining stock from authorized distributors or secondary market suppliers. Ensure that any sourced units are genuine Renesas products with intact packaging to guarantee reliability in critical timing applications.

Selection Notes

Select this component when designing systems requiring four independent differential clocks derived from a single reference. It is suitable for designs needing flexible output standards (LVDS/LP-HCSL) and precise jitter specifications. Consider the 24-VFQFPN package constraints and verify that the required output frequencies fall within the 1 MHz to 325 MHz range supported by the device architecture.

Part Context

The 9FGV1004BQ500LTGI belongs to the 9FGV1004 series, which offers factory-configurable options for various output frequencies and protocols. This series is part of the broader PhiClock portfolio, emphasizing ease of integration through I²C configurability and hardware pin selection. It serves as a specialized solution for complex multi-clock requirements in PCIe and server environments.

Replacement Considerations

Direct replacements may include other models within the 9FGV1004C series or the 9FGL04x1 series for newer designs. Verify pinout compatibility and output signal integrity when substituting with newer generations like the 9FGL0441DKILF, which supports higher PCIe generations.
