This dual-mode capability means a single part can serve both a clean, synthesised clock tree and a low-latency fanout path on the same board. It accepts two HCSL inputs and distributes them to twelve HCSL outputs, all differential — the 2:12 ratio gives enough fanout for a PCIe reference clock tree feeding multiple endpoints from one device. The maximum output frequency hits 400 MHz, which covers PCIe Gen 1 through Gen 4 reference clock rates and most SerDes PLL reference requirements. ## Supply rail and temperature — the operating envelope The supply voltage is 3.135 V to 3.465 V — a tight 3.3 V nominal range. The PLL's jitter performance is sensitive to supply noise; a clean 3.3 V rail with less than 50 mV ripple is expected for the datasheet jitter numbers to hold. ## Active lifecycle — no LTB clock ticking The single-circuit design means one PLL core per package — no shared resources between channels, so each output pair sees independent jitter from the others. No stock-holding claim; the part is procured per order.","metaTitle":"Renesas 9ZML1252EKILF PLL Clock Generator, 400 MHz","metaDescription":"Active Renesas 9ZML1252EKILF PLL clock generator with bypass, 400 MHz max, 2:12 HCSL I/O, 72-VFQFN.

The 9ZML1252EKILF's PLL with bypass means it can clean jitter and synthesise frequencies, which the 5P1105 cannot. For a direct PLL-based replacement, the 5P49V6965A000NLGI (VersaClock 6E) shares the PLL with bypass feature but has a different output count and frequency ceiling."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9ZML1252EKILF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9ZML1252EKILF when reusing this data.
