It accepts a wide range of differential and single-ended input standards — CML, HCSL, LVCMOS, LVDS, and LVPECL — making it a universal front-end for clock trees that must interface with different logic families on the same board. With a maximum frequency of 2 GHz, this buffer sits comfortably in the signal chain for 10G/25G Ethernet, PCIe Gen 4/5 reference clocks, and high-speed ADC/DAC sampling clocks. The 2:8 input-to-output ratio means two independent clock sources can each fan out to four destinations, or one source can drive all eight outputs — a common configuration for distributing a clean reference across multiple ASICs or FPGAs.","metaTitle":"TI LMK1D1208PRHAR Fanout Buffer, 2 GHz, 40-VQFN","metaDescription":"Texas Instruments LMK1D1208PRHAR 8-channel fanout buffer, 2 GHz max, LVDS outputs, 2:8 ratio, 1.8V/2.5V/3.3V supply, -40 to 105°C, active production, ROHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Mfr":"Texas Instruments","Type":"Fanout Buffer (Distribution)","Input":"CML, HCSL, LVCMOS, LVDS, LVPECL","Output":"LVDS","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"40-VFQFN Exposed Pad","Product Status":"Active","Frequency - Max":"2 GHz","lifecycle_stage":"eol_hot","Voltage - Supply":"1.71V ~ 1.89V, 2.375V ~ 2.625V, 3.135V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"2:8","Operating Temperature":"-40°C~105°C(TA)","Supplier Device Package":"40-VQFN (6x6)","Differential - Input:Output":"Yes/Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.3900","priceTiers":[{"qty":1,"price":"$11.39000","currency":"USD"},{"qty":10,"price":"$10.46400","currency":"USD"},{"qty":25,"price":"$10.03040","currency":"USD"},{"qty":100,"price":"$8.83770","currency":"USD"},{"qty":250,"price":"$8.40396","currency":"USD"},{"qty":500,"price":"$7.86176","currency":"USD"},{"qty":1000,"price":"$7.67250","currency":"USD"},{"qty":2500,"price":"$7.67250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f9e9a7a14ed1a7646a8278bda362c097.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LMK1D1208PRHAR/alternatives.json"},"ai":{"faq":[{"question":"What input signal types does the LMK1D1208PRHAR accept?","answer":"The buffer accepts CML, HCSL, LVCMOS, LVDS, and LVPECL input standards.
