It accepts a crystal input and delivers up to 19 differential clock outputs at frequencies up to 400 MHz, covering the reference-clock needs of PCIe Gen1/2/3 and Intel CPU host-bus interfaces. The single 3.135 V to 3.465 V supply and industrial temperature range (-40°C to 85°C) suit it for embedded motherboards, industrial PCs, and telecom line cards that need a clean, low-jitter clock tree from one fanout device. The 56-TSSOP package is a standard footprint for CK505-family parts. ## 19 clock outputs from one crystal — fanout planning A 1:19 input-to-output ratio means a single 25 MHz or 27 MHz crystal can feed nineteen clock loads — CPU, PCH, PCIe slots, SATA, USB 3.x, LAN controllers — without external fanout buffers. The differential outputs (No/Yes) are HCSL-compatible for PCIe reference clocks; the single-ended outputs serve legacy peripherals. When laying out the board, note that all nineteen outputs share the same PLL core, so any output frequency change requires reprogramming the entire device — not per-output independent synthesis. ## 400 MHz ceiling — PCIe generation support The 400 MHz maximum frequency covers the 100 MHz base reference for PCIe Gen1/2/3, plus the 133 MHz and 200 MHz clocks used by Intel CPU host interfaces and memory controller hubs. It does not natively generate the 25 MHz or 48 MHz USB/SATA reference — those are derived from the crystal input and internal dividers. For PCIe Gen4 (16 GT/s) the reference clock spec tightens jitter requirements; the 9LPRS525AGILF datasheet should be checked against the Gen4 clocking spec before committing a new design. ## Active, ROHS3, industrial temp — no obsolescence risk Renesas lists the 9LPRS525AGILF as Active with ROHS3 compliance. The -40°C to 85°C operating range is wider than the commercial 0°C to 70°C grade found on many CK505 parts, making this variant suitable for outdoor telecom, industrial motor drives, and automotive infotainment head units that see temperature cycling. The 56-TSSOP package is a standard surface-mount footprint; no special handling beyond MSL 3 bake-out is expected.","metaTitle":"9LPRS525AGILF CK505 PLL Clock Generator, 400 MHz, 19 Outputs","metaDescription":"9LPRS525AGILF CK505 clock generator IC from Renesas.

The 9ZXL0851EKKLF and 9ZXL1231EKILF are also CK505-family PLLs from Renesas with differential HCSL outputs and 400 MHz maximum frequency, but they have 1:8 and 1:12 input-to-output ratios respectively — fewer fanout outputs than the 1:19 of the 9LPRS525AGILF. The 9DB803DFLFT is a PCIe-only clock generator with 1:8 ratio and commercial temperature range (0°C to 70°C).

The differential outputs are HCSL-compatible for PCIe; single-ended outputs serve other peripherals."},{"question":"Is 9LPRS525AGILF compatible with Intel Coffee Lake or newer platforms?","answer":"The part is a CK505 clock generator designed for Intel CPU and PCIe buses. Compatibility with Coffee Lake or newer platforms depends on the specific clocking requirements (frequency plan, output count, jitter specs) of that platform. The 400 MHz maximum frequency covers the 100 MHz PCIe reference and CPU host clocks used through Skylake and Kaby Lake generations. For Coffee Lake and later, verify the platform's CK505 compatibility and jitter budget against the datasheet before design-in."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9LPRS525AGILF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9LPRS525AGILF when reusing this data.
