It targets Intel CPU server platforms, PCI Express reference clocks, and SATA timing. The 1:9 fanout ratio means one clean reference source can drive multiple PCIe root ports or SATA controllers without adding separate buffers — a common topology on server motherboards where board space is tight and skew between lanes must stay low. ## 400 MHz ceiling and differential output discipline Maximum output frequency is 400 MHz, which covers PCIe Gen1 through Gen4 reference clock requirements (100 MHz base with spread-spectrum) and SATA at 150/300/600 MHz rates. The differential output (HCSL) is standard for PCIe — single-ended inputs are accepted, so a crystal or LVCMOS clock source works without level translation. A clean 3.3 V rail with low ripple is expected; sharing this rail with a switching regulator without adequate decoupling can push the PLL jitter above the PCIe mask. ## 48-TSSOP footprint — reflow and placement notes Housed in a 48-TFSOP (0.240\", 6.10 mm width) package, also listed as 48-TSSOP. The 0.50 mm lead pitch is standard for this density — no exotic stencil or reflow profile required. Check the MSL rating before the first production run; a high MSL level means a bake step before reflow to avoid popcorning. Not rated for extended industrial or automotive temperature ranges.","metaTitle":"9FG108EGLF Renesas Clock Generator IC – 400 MHz, HCSL","metaDescription":"Renesas 9FG108EGLF PLL clock generator for Intel CPU server, PCIe, SATA. 400 MHz max, 1:9 HCSL outputs, 3.3 V supply, 48-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"PLL":"Yes","Input":"Clock, Crystal","Output":"HCSL","Package":"Tube","Main Purpose":"Intel CPU Server, PCI Express (PCIe), SATA","Mounting Type":"Surface Mount","Package / Case":"48-TFSOP (0.240\\\", 6.10mm Width)","Frequency - Max":"400MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"1:9","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"48-TSSOP","Differential - Input:Output":"No/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.7","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.70000","currency":"USD"},{"qty":10,"price":"$7.86300","currency":"USD"},{"qty":25,"price":"$7.49680","currency":"USD"},{"qty":100,"price":"$6.50950","currency":"USD"},{"qty":250,"price":"$6.21688","currency":"USD"},{"qty":500,"price":"$5.76150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/eab3ed43da54d492c76f34893e4afc02.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for 9FG108EGLF — 9DB803DFLFT?","answer":"The 9DB803DFLFT is a peer from Renesas with the same HCSL output type and 400 MHz maximum frequency, but its input-to-output ratio is 1:8 versus the 9FG108EGLF's 1:9.
