9FGV1008B205LTGI

Overview

The 9FGV1008B205LTGI is a programmable PhiClock generator from Renesas Electronics, designed for high-performance timing applications. It features six outputs supporting LP-HCSL and LVDS signaling formats. The device operates with a supply voltage of 1.8V or 3.3V and accepts crystal inputs in the 50 MHz range. It supports PCIe Gen1 through Gen4 jitter compliance standards. The component is housed in a 24-pin LGA package (LTG24) with dimensions of 4.0 x 4.0 x 1.4 mm. It includes spread-spectrum input acceptance capabilities and offers four differential outputs alongside two single-ended outputs.

Feature Summary

• Programmable clock generation with hardware selection via select pins or I²C software control
• Supports LP-HCSL and LVDS output signaling types for flexible interface compatibility
• Complies with jitter requirements for PCIe Gen1, Gen2, Gen3, and Gen4 standards
• Accepts spread-spectrum input signals to reduce EMI emissions

Applications

• PCI Express (PCIe) system clock distribution
• High-speed data communication interfaces requiring low-jitter timing
• Server and storage systems utilizing SATA or SAS protocols
• Networking equipment requiring precise clock synchronization

Procurement Notes

Verify the specific suffix B205LTGI against official Renesas documentation to confirm factory configuration details. Ensure the LTG24 package type matches the target PCB footprint. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component when six outputs are required with mixed LP-HCSL and LVDS capabilities. Verify that the 1.8V or 3.3V core voltage aligns with the system power rails. Ensure the design accommodates the 4.0 x 4.0 mm LGA footprint. Confirm that the input frequency range matches the available crystal oscillator specifications.

Part Context

This part belongs to the 9FGV100xPhiClock family, which provides programmable clock solutions for high-speed digital interfaces. The PhiClock series is optimized for applications demanding strict jitter performance and flexible output configurations. It serves as a critical timing source for modern computing and communication platforms.

Replacement Considerations

Direct substitutes within the same family include other 9FGV100x variants such as 9FGV1002, 9FGV1004, or 9FGV1006, depending on the required number of outputs and specific frequency configurations. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
