It accepts ECL or PECL inputs and delivers two matched ECL/PECL outputs, maintaining signal integrity up to 3.8 GHz. The part operates from a 2.375 V to 3.8 V supply, covering common 2.5 V and 3.3 V logic rails, and is specified across the industrial temperature range of -40°C to 85°C. Typical applications include clock fan-out in telecom switches, data center switches, test equipment, and any serial link requiring low-skew distribution of a high-frequency reference. ## Supply range and differential I/O — what they mean for your design The 2.375 V to 3.8 V supply range lets this buffer run directly from a 2.5 V or 3.3 V rail without an external regulator, simplifying power-tree design. Because both input and output are differential ECL/PECL, the part mates directly to common high-speed clock sources (e.g., LVDS oscillators with AC coupling, or PECL VCXOs) and to downstream ECL/PECL loads such as SerDes reference inputs or FPGA clock pins. The differential path also gives common-mode noise rejection, important when the buffer sits near switching regulators or on a noisy backplane. ## Package and footprint Housed in an 8-pin SOIC package (8-SOIC, 0.154\" body width, 3.90 mm), the SN65LVEP11DR uses a standard surface-mount footprint compatible with automated assembly. No exposed pad or thermal via is required at the rated dissipation levels. The -40°C to 85°C operating range covers most industrial and telecom environments. ## Lifecycle and sourcing It is ROHS3 compliant. For dual-sourcing or higher fan-out requirements, the CDCLVP1204RGTR offers a 2:4 LVPECL fanout buffer in a similar supply range, though it uses a different package (QFN) and is not a pin-for-pin drop-in. Sourcing is confirmed through independent distribution; availability and current pricing are quoted against an RFQ.","metaTitle":"SN65LVEP11DR 1:2 Fanout Buffer, 3.8 GHz, 8-SOIC","metaDescription":"TI SN65LVEP11DR 1:2 differential fanout buffer, 3.8 GHz max frequency, 2.375V–3.8V supply, ECL/PECL I/O, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution)","Input":"ECL, PECL","Output":"ECL, PECL","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"3.8 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 3.8V","Number of Circuits":"1","Ratio - Input:Output":"1:2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SOIC","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.09","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.09000","currency":"USD"},{"qty":10,"price":"$4.57000","currency":"USD"},{"qty":25,"price":"$4.32000","currency":"USD"},{"qty":100,"price":"$3.74400","currency":"USD"},{"qty":250,"price":"$3.55200","currency":"USD"},{"qty":500,"price":"$3.18722","currency":"USD"},{"qty":1000,"price":"$2.68801","currency":"USD"},{"qty":2500,"price":"$2.55361","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9752760aeaa7906751edd357e5024664.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does SN65LVEP11DR support differential inputs and outputs?","answer":"Yes, both the input and output are differential, and the part accepts ECL or PECL levels on the input side while delivering ECL/PECL outputs."},{"question":"Is SN65LVEP11DR compatible with LVPECL?","answer":"The part uses ECL/PECL I/O levels.
