- Using the LMK0480x/LMK04906 for Hitless Switching and HoldoverPDF, 3.8 Mb, Archivo publicado: jul 12, 2013
This application report discusses some of the key performance results when using LMK0480x/LMK04906to implement hitless switching between reference clocks. Hitless Switching is required in certainapplications such as SONET/SDH/line port cards and routers/switchers in order to minimize thepropagation of phase transients to the clock outputs during reference clock switching.
