The 3:11 ratio is the key parametric: it replaces a separate mux plus a multi-output fanout tree, saving board space and reducing additive jitter from cascaded buffers. The 2 GHz max frequency covers PCIe Gen4/5 reference clocks, 10GbE, Fibre Channel, and 100G backplane distributions. The differential input and output path keeps signal integrity clean across the fanout tree — single-ended clocking would limit reach and noise margin at these speeds. ## Supply range and temperature grade — board-level fit Supply voltage spans 2.375 V to 3.465 V, covering both 2.5 V and 3.3 V rails without an extra regulator. ## Active production — no obsolescence pressure The BOM line can be committed without an obsolescence risk flag — sourced per RFQ against the required quantity.","metaTitle":"8T39S11ANLGI Renesas Clock Buffer 3:11 2 GHz 48-VFQFN","metaDescription":"Renesas 8T39S11ANLGI fanout buffer/multiplexer, 3:11 ratio, 2 GHz max, HCSL/LVDS/LVPECL outputs, -40°C to 85°C, 48-VFQFPN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution), Multiplexer","Input":"HCSL, HSTL, LVDS, LVPECL, Crystal","Output":"HCSL, LVDS, LVPECL","Package":"Tray","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Frequency - Max":"2 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"3:11","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"48-VFQFPN (7x7)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.77","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$19.77000","currency":"USD"},{"qty":10,"price":"$18.16700","currency":"USD"},{"qty":25,"price":"$17.41360","currency":"USD"},{"qty":80,"price":"$15.34288","currency":"USD"},{"qty":260,"price":"$14.82962","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0f90833b352e3f4d2c81edde4e4d2843.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 8T39S11ANLGI compatible with HCSL outputs?","answer":"Yes — the outputs are configurable as HCSL, LVDS, or LVPECL. HCSL is the common choice for PCIe reference clocks; LVDS suits backplane distribution; LVPECL is typical in high-speed serial links."},{"question":"Is 8T39S11ANLGI compatible with LVPECL inputs?","answer":"Yes — the input stage accepts LVPECL, along with HCSL, HSTL, LVDS, and a crystal. The crystal input allows a local oscillator to be the clock source without an external XO buffer."},{"question":"What are the direct alternatives for 8T39S11ANLGI?","answer":"The closest functional sibling in the same family is the 8SLVP1204ANLGI8 — a 2:4 fanout buffer with LVPECL outputs, also 2 GHz, same supply range (2.375 V), same temperature grade. The 8T39S11ANLGI offers a 3:11 ratio with multiplexer and three output types (HCSL/LVDS/LVPECL) versus the 8SLVP1204's 2:4 ratio and LVPECL-only output.
