9FGV1005A000LTGI8

Overview

The 9FGV1005A000LTGI8 is a factory-configured programmable clock generator from Renesas Electronics' PhiClock family. It provides two output pairs with one integer-related frequency and one spread-spectrum or fractional frequency per configuration, plus two crystal reference copies. The device supports LP-HCSL and LVDS differential signaling standards with supply voltages of 1.8V and 3.3V. It operates within a temperature range of -40°C to 85°C and utilizes a 24-lead LGA package measuring 4.0 x 4.0 mm.

Feature Summary

• Factory-configurable PhiClock architecture supporting hardware selection via select pins or software control via I²C
• Dual output pairs providing integer and spread-spectrum/fractional frequencies alongside crystal reference outputs
• Supports LP-HCSL and LVDS differential output signaling standards
• Compatible with PCIe Gen1 through Gen4 jitter compliance requirements

Applications

• PCI Express timing solutions for Gen1 through Gen4 interfaces
• High-performance computing systems requiring precise clock distribution
• Telecommunications equipment utilizing low-jitter clock generation

Procurement Notes

This component is a factory-configured device, meaning specific electrical parameters are determined at the time of manufacturing based on customer specifications. Verification should focus on confirming the exact output frequencies and configurations match the design requirements, as generic datasheets do not define these unique values. Ensure the package type and voltage levels align with the target system constraints before procurement.

Selection Notes

Select this model when a dual-output clock generator with mixed integer and spread-spectrum capabilities is required for PCIe or similar high-speed serial links. Verify that the 1.8V and 3.3V supply rails are available in the target design. Consider the 24-lead LGA package dimensions (4.0 x 4.0 mm) for PCB layout compatibility. Confirm that the factory configuration process can accommodate the specific frequency plan needed for the application.

Part Context

The 9FGV1005A000LTGI8 belongs to the 9FGV1005C series within the PhiClock family. This series is designed for applications requiring flexible clock generation with support for multiple output standards. The 'A' suffix typically denotes a specific factory configuration variant within the broader 9FGV1005 product line, sharing common architectural features with other members like the 9FGV1004 and 9FGV1006.

Replacement Considerations

Direct replacements within the same family include the 9FGV1004CQ501LTGI8 and 9FGV1006Q550LTGI8, though pinouts and output configurations may differ. Verify that any substitute part supports the required LP-HCSL or LVDS outputs and matches the 1.8V/3.3V supply requirements. Cross-model substitution requires careful review of the specific factory configuration data.
