9FG1201HGLFT

Overview

The Renesas 9FG1201HGLFT is a PCIe clock distribution IC designed for memory, DIMM, and PCI Express applications. It operates with a single circuit providing a 1:12 input-to-output ratio. The device accepts an HCSL clock input and generates twelve differential HCSL outputs. It supports maximum frequencies up to 400MHz and functions within a supply voltage range of 3.135V to 3.465V. The component utilizes a Phase-Locked Loop (PLL) and is housed in a 56-TFSOP surface-mount package. It is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Provides 1:12 clock distribution with differential HCSL outputs
• Supports maximum frequency of 400MHz for PCIe and memory systems
• Integrated PLL for stable clock generation
• Operates on 3.135V to 3.465V supply voltage

Applications

• PCI Express (PCIe) clock distribution
• Memory module clocking
• DIMM interface timing

Procurement Notes

This component is officially listed as End-of-Life (EOL). Verification of current availability requires checking distributor inventory status directly. No new production units are expected from the manufacturer. Buyers should confirm the specific revision level and packaging type (Tape & Reel) against their bill of materials before procurement attempts.

Selection Notes

Select this part only if a 1:12 fan-out ratio with HCSL signaling is required for legacy or specific PCIe/memory designs. Ensure the design accommodates the 56-TFSOP package dimensions. Verify that the 0°C to 70°C temperature range meets system requirements, as industrial variants may not be available for this EOL part.

Part Context

The 9FG1201HGLFT belongs to the ICS9FG1 series of clock generators and buffers by Renesas. This series targets high-speed digital interfaces requiring precise timing. The 'H' suffix typically denotes specific performance or package variations within the family, while 'GLFT' indicates lead-free RoHS compliance and tape-and-reel packaging.

Replacement Considerations

As the part is discontinued, direct substitutes must be sourced from Renesas or third-party distributors. Potential replacements include other members of the 9FG1 series or newer Renesas clock buffer families supporting similar pin counts and HCSL output configurations.
