9FGV1004BQ538LTGI

Overview

The 9FGV1004BQ538LTGI is a programmable clock generator from Renesas Electronics' PhiClock family, designed for low phase-noise 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 output frequencies up to 325 MHz with a maximum input frequency of 240 MHz. Packaged in a 24-pin VFQFPN format, it exhibits a typical jitter of 27 ps and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Four programmable differential outputs supporting LP-HCSL and LVDS standards
• Low phase noise performance with 27 ps typical jitter
• Flexible power supply operation between 1.71 V and 3.465 V
• Supports integer and fractional/spread-spectrum configurations

Applications

• PCI Express compliant system clock generation
• High-speed data communication interfaces
• Server and storage subsystem timing
• Industrial control systems requiring precise clocking

Procurement Notes

Verify the specific suffix 'BQ538' against official Renesas documentation to confirm factory configuration details. Check current lifecycle status as some variants may be discontinued or subject to long lead times. Ensure compatibility with existing PCB footprints for the 24-VFQFPN package before procurement.

Selection Notes

Select this component when LP-HCSL or LVDS output drivers are required for high-speed serial links. Confirm that the 325 MHz maximum output frequency meets system requirements. Verify I²C address availability if multiple clock generators are used on the same bus. Consider thermal dissipation within the compact VFQFPN package during layout.

Part Context

This part belongs to the 9FGV1004 series, which provides configurable clock solutions for PCIe and other high-speed interfaces. The PhiClock family allows hardware or software selection of output configurations via select pins or I²C commands. Factory-programmed options eliminate the need for external configuration components in mass production.

Replacement Considerations

Direct substitutes include other 9FGV1004 variants with different output frequencies or packaging options. Cross-reference pinouts and electrical specifications carefully when replacing with generic clock generators. Ensure any alternative supports the required LP-HCSL/LVDS standards and jitter performance.
