The differential input-to-output path means the buffer preserves signal integrity for high-speed differential clocks, critical for jitter-sensitive applications like SERDES reference clocks.","metaTitle":"Texas Instruments LMK1D1212RHAR Clock Buffer, 2 GHz","metaDescription":"Texas Instruments LMK1D1212RHAR clock buffer, 2 GHz max frequency, 2:12 fanout, LVDS outputs, industrial temp range.
