Overview
The LMK00804BPWR is a low skew, high performance clock fanout buffer produced by Texas Instruments. This component is designed to distribute up to four LVCMOS/LVTTL outputs from one of two selectable inputs, which can accept differential or single-ended inputs. The device is particularly suited for applications requiring high performance and repeatability due to its low additive jitter, phase noise floor, and guaranteed output and part-to-part skew characteristics.
