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.","metaTitle":"Renesas 9ZXL0852EKILF PLL Clock Buffer, 400 MHz, 1:8 HCSL","metaDescription":"Renesas 9ZXL0852EKILF PLL clock buffer for Intel QPI and PCI Express. 400 MHz max, 1:8 HCSL fanout, -40 to 85°C.
