It is a single-circuit device in a 20-TSSOP package, designed for clock distribution in telecom infrastructure, data converters, FPGA reference clock trees, and high-speed backplane applications where a clean LVPECL fanout is needed from a mixed-signal environment. ## Input flexibility — the real selection driver The 2:4 fanout ratio means one input channel can be distributed to four LVPECL loads, or the internal mux selects between two input sources for redundancy or clock-source failover. The wide input protocol support is the differentiating feature: a single BOM line can terminate CML from a SerDes, LVDS from an FPGA, or LVPECL from a high-speed ADC without external level-shifting resistors or translator parts. The 650 MHz ceiling covers gigabit-class SerDes reference clocks and most FPGA transceiver reference frequencies. ## 3.3V supply — plan the rail budget The supply range is 3.135 V to 3.465 V, a tight 3.3 V ±5 % window. This is not a wide-range 2.5 V to 5.5 V part; the rail needs to stay clean and within regulation. The differential input-to-output path is fully differential (Yes/Yes), so the part preserves signal integrity through the buffer without single-ended conversion. The industrial temperature range of -40°C to 85°C covers outdoor base stations, motor-drive cabinets, and uncontrolled telecom shelters. ## Active lifecycle — no LTB clock ticking The 8533AGI-01LFT carries an Active product status and ROHS3 compliance. For a production BOM this means no forced redesign cycle from obsolescence; the part can be qualified into new designs with confidence that the supply channel will remain open. The 20-TSSOP footprint is a standard body size (4.40 mm width), shared across the Renesas clock-buffer family, so a layout change for a different fanout ratio or output standard stays pin-compatible across the 20-pin TSSOP variants. ## Sourcing this part to your BOM The 8533AGI-01LFT is sourced through independent distribution channels and quoted to order against an RFQ. For small quantities, the cut-tape option avoids reel minimums.","metaTitle":"IDT 8533AGI-01LFT Clock Buffer, 2:4 Fanout, 650 MHz","metaDescription":"IDT 8533AGI-01LFT fanout buffer/multiplexer: 2:4 ratio, 650 MHz max, LVPECL output, accepts CML/HCSL/LVDS/LVHSTL/LVPECL/SSTL inputs. 3.3V supply, -40°C to 85°C.","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":"CML, HCSL, LVDS, LVHSTL, LVPECL, SSTL","Output":"LVPECL","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Frequency - Max":"650 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":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.93","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.93000","currency":"USD"},{"qty":10,"price":"$13.72300","currency":"USD"},{"qty":25,"price":"$13.15440","currency":"USD"},{"qty":100,"price":"$11.59000","currency":"USD"},{"qty":250,"price":"$11.02112","currency":"USD"},{"qty":500,"price":"$10.31008","currency":"USD"},{"qty":1000,"price":"$9.45683","currency":"USD"},{"qty":3000,"price":"$9.10131","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/646f3c2083fb44d7eeb2886af58f91d6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 8533AGI-01LFT compatible with 3.3V logic?","answer":"Yes, the supply range is 3.135 V to 3.465 V, which is a standard 3.3 V ±5 % rail. The input accepts CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL — all common 3.3 V differential signaling standards. No external level translation is needed for those signal types."},{"question":"What is the maximum frequency of 8533AGI-01LFT?","answer":"The maximum frequency is 650 MHz. This covers most FPGA transceiver reference clocks, gigabit Ethernet SerDes, and high-speed ADC/DAC sampling clocks. For applications above 650 MHz, the Renesas 8SLVP1204ANLGI8 family runs to 2 GHz but uses a 20-QFN package."},{"question":"Can 8533AGI-01LFT replace 8533AGI-01LF?","answer":"The 8533AGI-01LFT and 8533AGI-01LF share the same die and electrical specifications. The difference is packaging and shipping format: the -01LFT suffix indicates Tape & Reel packaging, while the -01LF suffix typically ships in tube or tray. Electrically they are identical — same 650 MHz ceiling, same input/output standards, same 20-TSSOP package body. The -01LFT is the reeled variant intended for automated pick-and-place assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/8533AGI-01LFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/8533AGI-01LFT when reusing this data.
