The input stage accepts CML, HCSL, LVCMOS, LVDS, or LVPECL, so this single part can bridge between a PLL output and a downstream FPGA or SerDes without a translator. The output is fixed LVDS, which is the de facto standard for differential clock distribution on most mid-to-high-speed boards. ## Industrial temperature and package Sourced per RFQ against your BOM quantity.","metaTitle":"LMK1D1208IRHAR Clock Buffer – 2:8 LVDS, 2 GHz","metaDescription":"Texas Instruments LMK1D1208IRHAR clock buffer: 2:8 fanout, LVDS output, 2 GHz max, -40°C to 105°C, 40-VQFN.
