The spurs depend on how you are reprogramming the si5351 to shift the frequency. Phase change is virtually spur free, reprogramming just the vco is smooth. Resetting the PLL is very bumpy. On qrplabs groups.io as well te.bitx20 list, Hans wrote a brilliant post on Si5351. It is a primer on how to program Si5351. - f
