Harmonics from a Si5351A is not a problem. As pointed out a LPF will do what it takes to get the fundamental frequency "extracted". The Si5351A is designed to clock/feed other digital circuits so that shouldn't be a problem in this particular case either.
In the digital clock domain spurs are, in most of the cases, not important. But in the RF domain things are VERY different. Unfortunately there seems to be a trend that only harmonics are important when in fact the in-band spurs are the important ones and what disturbs other stations and own receivers too. In the RFzero <http://www.rfzero.net/documentation/rf/> that also uses a Si5351A great attention has been devoted to keeping spurs and especially in-band down.
