Product details

1:8 PLL fanout for PCIe and QPI clock trees

The Renesas 9ZXL0852EKILF is a PLL-based clock buffer that takes one differential input and delivers eight HCSL outputs at up to 400 MHz. It is designed specifically for Intel QPI and PCI Express (PCIe) reference clock distribution, which means the output jitter and skew specs are tuned for those bus standards rather than generic clocking. The 1:8 fanout ratio lets a single oscillator feed eight downstream devices — a typical PCIe root complex to multiple endpoint slots, or a QPI link between CPU and chipset.

DB800ZL derivative — what the description line means

The description field reads "DB800ZL 'LITE' OEM DERIV + WRTLK". This is a derivative of Renesas' DB800ZL zero-delay buffer family, stripped down to a 'LITE' feature set for cost-sensitive OEM builds.

Active lifecycle — no end-of-life concern

The 9ZXL0852EKILF carries an Active product status. For a BOM line feeding a PCIe clock tree, this is the right lifecycle tier — you can qualify it into production without worrying about a forced redesign mid-run.

Frequently asked questions

What is the 9ZXL0852EKILF used for?

It is a PLL clock buffer for Intel QPI and PCI Express (PCIe) reference clock distribution. It takes one differential input and fans it out to eight HCSL outputs at up to 400 MHz.

How does the 9ZXL0852EKILF compare to the 9ZXL1231EKILF?

Both are Renesas PLL clock buffers for Intel QPI and PCIe with the same 400 MHz max frequency, HCSL outputs, and industrial temperature range. The 9ZXL0852EKILF has a 1:8 input-to-output ratio, while the 9ZXL1231EKILF has a 1:12 ratio — choose the 9ZXL0852 when you need eight outputs and the 9ZXL1231 when you need twelve.

What is the closest functional equivalent to the 9ZXL0852EKILF?

The 9ZXL0851EKKLF is the closest functional equivalent — same PLL architecture, same HCSL output type, same 400 MHz max frequency, same 1:8 ratio, and the same Intel QPI / PCIe purpose. The main difference is the suffix, which may indicate a different configuration or register lock setting.
