Just noticed Valon has a new synthesizer module 5007 with very similar output range to the ADF4350, but the photo is not high enough resolution to see if that is indeed what's on there. http://www.valontechnology.com/products.html I wonder if the NRAO linux driver for Valon would work for this.
Dave, Valon does not give a jitter spec, they just point to online phase noise to jitter calculations. I'll calculate it sometime later.
