It is designed for the Intel CPU server clock tree, PCI Express reference clocks, and SATA interfaces — the kind of timing distribution you find on a motherboard or add-in card where the platform calls for a dedicated HCSL fanout buffer with integrated PLL cleaning. The input side accepts either a single-ended clock or a fundamental-mode crystal, so you can feed it from an onboard oscillator or a discrete crystal without an extra buffer stage. The outputs are differential HCSL — the standard for PCIe reference clocks — and the part generates them from a non-differential input, which saves a differential oscillator on the BOM. Supply range is 3.135 V to 3.465 V. Operating temperature is -40°C to 85°C. ## 400 MHz and HCSL — what the output spec means for PCIe generation Maximum output frequency is 400 MHz. Output type is HCSL. Input-to-output ratio is 1:5. ## Package and footprint — 28-TSSOP Package is 28-TSSOP with 4.40 mm width. ## Lifecycle and sourcing The 9FG104EGILF carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"9FG104EGILF Clock Generator, PLL, HCSL Output, 400MHz","metaDescription":"9FG104EGILF PLL clock generator IC from Renesas.

PCIe Gen4 typically requires tighter jitter specifications that may exceed this part's rated performance. Check the jitter specs in the datasheet against your Gen4 controller requirements."},{"question":"What is the closest functional second-source to 9FG104EGILF?","answer":"The 9ZXL0851EKKLF is a similar Renesas PLL with HCSL output and 400 MHz maximum frequency, but it has a 1:8 fanout ratio and differential inputs. The 9DB803DFLFT is another HCSL PCIe clock generator but is commercial temperature (0°C to 70°C) and comes in a different package. Neither is a drop-in replacement — verify pin compatibility and electrical specs before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/9FG104EGILF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/9FG104EGILF when reusing this data.
