That input-to-output conversion is the key differentiator: most clock buffers either pass through differential or single-ended on both sides. Here, the single-ended-to-differential translation happens on-chip, saving an external translator and the associated PCB area and skew. It lives in a 20-TSSOP package, runs from a 3.135V to 3.465V rail, and is rated across the industrial temperature range of -40°C to 85°C. ## The 266 MHz ceiling — where it fits and where it doesn't The 266 MHz maximum frequency sets a clear boundary. This part is sized for PCIe Gen 1 reference clocks, Gigabit Ethernet, FPGA transceiver reference clocks at 125-156.25 MHz, and general-purpose system clock distribution at those rates. It will not retime a 312.5 MHz SerDes reference or a 400 MHz DDR5 clock — those need a higher-speed fanout like the 8SLVP1104 family that runs to 2 GHz. For the 266 MHz and below zone, the 8535AGI-31LF is a clean fit with margin on the edge rates. ## Active and available — no LTB clock ticking The 8535AGI-31LF carries an Active lifecycle status and is ROHS3 compliant. There is no end-of-life notice, no last-time-buy window to track. For a production clock tree that needs to ship for the next several years, this part does not introduce obsolescence risk.","metaTitle":"8535AGI-31LF Clock Buffer, 2:4 Fanout, 266 MHz, LVPECL","metaDescription":"Renesas 8535AGI-31LF fanout buffer (distribution) and multiplexer. 2:4 ratio, 266 MHz max, LVPECL outputs, LVCMOS/LVTTL/crystal inputs, -40 to 85°C, 20-TSSOP.","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":"LVCMOS, LVTTL, Crystal","Output":"LVPECL","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Frequency - Max":"266 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3.135V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"2:4","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-TSSOP","Differential - Input:Output":"No/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.73","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.73000","currency":"USD"},{"qty":10,"price":"$10.59700","currency":"USD"},{"qty":25,"price":"$10.10400","currency":"USD"},{"qty":100,"price":"$8.77330","currency":"USD"},{"qty":250,"price":"$8.37896","currency":"USD"},{"qty":500,"price":"$7.63964","currency":"USD"},{"qty":1000,"price":"$6.65388","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5003f703e05cbc655bbeb5705c83c143.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the 8535AGI-31LF accept a differential input?","answer":"No. The inputs are single-ended only — LVCMOS, LVTTL, or a crystal.

The 8SLVP1104 is a 1:4 fanout with LVPECL outputs and differential inputs. Neither is a drop-in replacement — the input stage differs.
