34 | +Contraintes~: | |
35 | +\begin{itemize} | |
36 | +\item Si5351 impose une horloge d'entr\'ee entre 25~MHz et 26~MHz | |
37 | +\item RTL-SDR impose une horloge de 28,8~MHz | |
38 | +\item les horloges ultrastables imposent de fournir une r\'ef\'erence de 10~MHz | |
39 | +(ma\^\i tre) et un signal de synchronisation 1-PPS (ma\^\i tre) | |
40 | +\item les utilisateurs veulent recevoir un signal esclave \`a 10~MHz et un | |
41 | +signal de synchronisation esclave 1-PPS | |
