9FG1201HGLF

Application Specific Clock/Timing Overview

The 9FG1201HGLF is a clock distribution integrated circuit manufactured by Renesas Electronics Corporation. It functions as a PCIe clock generator and fan-out buffer, designed for memory, DIMM, and PCI Express applications. The device accepts an HCSL input signal and provides twelve HCSL outputs with a 1:12 ratio. Operating at a maximum frequency of 400 MHz, it utilizes an internal Phase-Locked Loop (PLL) and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 56-TFSOP package and operates within a commercial temperature range of 0°C to 70°C.

Application Specific Clock/Timing Feature Summary

• Provides 1:12 clock distribution ratio with 12 HCSL outputs
• Integrated PLL for clock generation up to 400 MHz
• Designed specifically for Memory, DIMM, and PCIe applications
• Operates on a single 3.135 V to 3.465 V power supply

Application Specific Clock/Timing Applications

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

Application Specific Clock/Timing Procurement Notes

The 9FG1201HGLF is listed as an obsolete or end-of-life product. Verification of current availability should be conducted through authorized distributors or secondary market suppliers. Engineering samples may not be available from the manufacturer. Designers should review the Product Change Notification (PCN) documents for any historical manufacturing changes before procurement.

Application Specific Clock/Timing Selection Notes

Select this component when a 1:12 HCSL fan-out buffer is required for PCIe or memory subsystems. Ensure the system design supports the 3.135 V to 3.465 V supply voltage range. The 56-TFSOP package dimensions must fit the PCB layout constraints. Since the part is obsolete, consider evaluating newer Renesas alternatives that offer similar pinouts and electrical specifications for new designs.

Application Specific Clock/Timing Part Context

This component belongs to the 9FG1201 family of clock generators. It is distinct from other Renesas parts like the 9FGP202AKLFT, which serves Intel CPU server applications with different output counts and packaging. The 9FG1201 series is specifically optimized for high-speed serial interface timing requirements in storage and expansion architectures.

Application Specific Clock/Timing Replacement Considerations

As the 9FG1201HGLF is marked as obsolete, direct replacement verification is required. Check Renesas documentation for cross-reference recommendations or updated families that maintain the 56-TFSOP footprint and 1:12 HCSL functionality. Verify compatibility with existing board layouts and firmware configurations if substituting.
