8316AKLFT

Overview

The 8316AKLFT is a clock buffer integrated circuit manufactured by Renesas Electronics Corporation, belonging to the 9ZXL series. It features an input-to-output ratio of 1:8 and supports differential signaling for both input and output stages. The device operates with a supply voltage range of 3.135V to 3.465V and is designed for high-frequency applications up to 400MHz. It utilizes HCSL output logic and is housed in a 48-VFQFPN (6x6) package with an exposed pad. The component is rated for industrial operating temperatures ranging from -40°C to 85°C and includes an internal Phase-Locked Loop (PLL).

Feature Summary

• 1:8 Input-to-Output Ratio with Differential I/O Support
• Maximum Frequency of 400MHz with Internal PLL
• HCSL Output Logic for Low Power Consumption
• Industrial Temperature Range (-40°C to 85°C)

Applications

• Intel QuickPath Interconnect (QPI) Clock Distribution
• PCI Express (PCIe) System Clock Buffering

Procurement Notes

Verify the exact suffix against manufacturer documentation, as '8316AKLFT' may represent a partial or variant designation within the 9ZXL family. Confirm moisture sensitivity level (MSL 3) and packaging type (Tape & Reel vs. Tray) based on the specific ordering code. Ensure compatibility with the 3.135V–3.465V supply voltage requirement during procurement planning.

Selection Notes

Select this component when a low-power, high-speed clock buffer is required for PCIe or QPI interfaces. The 400MHz maximum frequency and HCSL outputs make it suitable for modern high-bandwidth data paths. Ensure the design accommodates the 48-VFQFPN package thermal requirements and the specific 3.3V nominal supply voltage constraints.

Part Context

This part belongs to the Renesas 9ZXL series of zero-delay buffers, which are optimized for memory and peripheral clock distribution. The series is widely used in server and storage platforms requiring precise clock skew management. The 9ZXL0831 variants specifically target high-speed serial interface standards like PCIe Gen3/Gen4 and Intel QPI.

Replacement Considerations

Compatible substitutes within the same family include the 9ZXL0831EKKLFT and 9ZXL0831EKILFT. Verify that alternative parts match the 400MHz frequency specification and the 48-VFQFPN package dimensions. Check if the replacement offers the same HCSL output drive strength and temperature rating.
