The 1:8 fanout ratio means a single clean reference clock fans to eight destinations on the board without needing a separate distribution buffer for each lane — useful in multi-channel ADC arrays, FPGA banks, or backplane clock trees. Because the part has no internal PLL (PLL = No), it does not multiply or synthesize frequency — it conditions and redistributes the incoming clock, so the output jitter is bounded by the input quality and the device's additive jitter floor. ## Signal interface and supply tolerance Input accepts LVCMOS single-ended or LVDS/LVPECL differential; outputs are differential LVDS or LVPECL — the same output pair can be configured for either standard, which simplifies BOM consolidation when the board uses both logic families. Supply range is 3.15 V to 3.45 V — a tight 300 mV window. The 48-WQFN exposed pad (7x7 mm) needs a solid thermal via array under the paddle to keep the junction below the 85°C ceiling. ## Active lifecycle — no end-of-life risk on this BOM line For a production BOM that already uses this order code, there is no forced migration window. No stock-holding claim — quoted per the buyer's quantity.","metaTitle":"LMK03000ISQ/NOPB Clock Conditioner, 1.296 GHz, 1:8 fanout","metaDescription":"Texas Instruments LMK03000ISQ/NOPB Clock Conditioner, 1.296 GHz max, 1:8 fanout, LVDS/LVPECL outputs.
