The 800 MHz maximum frequency covers most high-speed serial clock distribution needs up to Gigabit Ethernet, FPGA reference clocks, and SERDES reference paths. Input accepts LVCMOS, LVPECL, or LVTTL levels; output can be LVCMOS or LVPECL. The differential input-to-output path (Yes/Yes) means it preserves signal integrity for LVPECL fanout without external level translation. ## Supply range and temperature grade Operates from 3V to 3.6V — a 3.3V nominal rail is the sweet spot. The 16-VFQFN exposed pad (3x3 mm) requires a thermal land on the PCB. The exposed paddle must be soldered to a ground plane for both electrical reference and heat sinking — a common oversight in first prototypes. ## Active production — no obsolescence watch Texas Instruments lists CDCM1802RGTT as Active. ROHS3 compliant. For BOM planning, this part carries no near-term end-of-life risk. Available in Tape & Reel (TR) and Cut Tape (CT) — the CT option is useful for prototype or low-volume builds where you want to avoid the full reel buy.","metaTitle":"CDCM1802RGTT Clock Buffer 1:2 800MHz 16QFN – Texas","metaDescription":"Texas Instruments CDCM1802RGTT fanout buffer/divider/mux, 800 MHz max, 1:2 ratio, LVCMOS/LVPECL I/O, 3V–3.6V, -40°C to 85°C, 16-VQFN exposed pad.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution), Divider, Multiplexer","Input":"LVCMOS, LVPECL, LVTTL","Output":"LVCMOS, LVPECL","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Frequency - Max":"800 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Number of Circuits":"1","Ratio - Input:Output":"1:2","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-VQFN (3x3)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.57","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.57000","currency":"USD"},{"qty":10,"price":"$11.55300","currency":"USD"},{"qty":25,"price":"$11.07360","currency":"USD"},{"qty":100,"price":"$9.75690","currency":"USD"},{"qty":250,"price":"$9.27804","currency":"USD"},{"qty":500,"price":"$8.67944","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/faffce7535bf4b780869d5462f3a3a80.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CDCM1802RGTT compatible with LVPECL inputs?","answer":"Yes. The input stage accepts LVPECL levels directly (along with LVCMOS and LVTTL). The output can also drive LVPECL loads.

The CDCM1802RGTT is a 1:2 buffer/divider/mux at 800 MHz. If you need a divider or a wider supply range, the CDCM1802RGTT fits; if you need more outputs or higher frequency, the CDCLVP1204RGTR is the alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CDCM1802RGTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CDCM1802RGTT when reusing this data.
