The 3:7 input-to-output ratio means three selectable inputs feed seven outputs, giving the system architect flexibility to route a reference clock to multiple loads without adding separate fanout trees. Input compatibility spans CML, HCSL, HSTL, LVDS, LVPECL, SSTL, and crystal — the widest signal-format set in this class. Outputs are available in HCSL, LVCMOS, LVDS, and LVPECL, so the same buffer can drive a PLL reference, a SerDes reference, and a logic clock from one input without external level translators. ## Frequency ceiling and differential path Rated for 3.1 GHz maximum frequency, the LMK00306SQX/NOPB covers the full range of high-speed serial standards — PCIe Gen4/5 reference clocks, 10G Ethernet, and JESD204B SYSREF. The differential input-to-output path is maintained throughout (Yes/Yes), so the signal integrity of a 100 MHz LVDS oscillator or a 312.5 MHz LVPECL SerDes reference is preserved without single-ended conversion loss. ## Package footprint and PCB layout The tape-and-reel packaging is the standard ordering code for automated assembly. The /NOPB suffix indicates lead-free / RoHS-compliant finish — no additional Pb-free qualification step is needed for the reflow profile.","metaTitle":"TI LMK00306SQX/NOPB Fanout Buffer, 3.1 GHz, 3:7, Active","metaDescription":"Texas Instruments LMK00306SQX/NOPB fanout buffer, multiplexer, translator. 3.1 GHz max, 3:7 ratio, industrial temp.
