9FG1200DG-1LFT

Overview

The 9FG1200DG-1LFT is a clock distribution IC manufactured by Renesas Electronics Corporation, designed for PCI Express and FBD applications. It operates with a maximum frequency of 400MHz and features a 1:12 input-to-output ratio. The device utilizes an HCSL input and provides HCSL outputs. It is housed in a 56-TFSOP package (56-TSSOP) and supports a supply voltage range of 3.135V to 3.465V. The component includes an internal PLL and functions as a fanout buffer.

Feature Summary

• Supports differential input and output signal transmission
• Integrates a Phase-Locked Loop (PLL) for clock generation
• Designed for high-speed data transfer environments

Applications

• PCI Express (PCIe) clock distribution
• FBD (Fully Buffered DIMM) memory systems
• Intel DB1200GS specification compliance

Procurement Notes

Verify the specific manufacturer part number against official Renesas documentation to ensure compatibility with system requirements. Confirm that the 56-TFSOP package type matches the target PCB layout. Check current product status, as availability may vary due to lifecycle changes or supply constraints. Ensure all electrical parameters align with design specifications before procurement.

Selection Notes

Select this component for designs requiring a 1:12 clock fanout with differential signaling. Ensure the operating environment stays within the specified temperature range. Verify that the power supply voltage falls within the 3.135V to 3.465V window. Consider the TSSOP package dimensions for mechanical fit. Confirm that the 400MHz maximum frequency meets the system's timing requirements.
