I wouldnt think theres much diference between the 1 and the 0 chips.
I'm doing a similar thing, my project is an off air standard at 10mc, the modules tend to use 20 to 30 Mc xtals, and produce around 10Kc to 200Mc, so with a clock of 10Mc's that ought to give 8Kc to 100Mc or so, that would be a nice little addition to a frequency standard.
Not sure how they work yet, in my system I also have 3Mc's available, so that might expand what I could do, and with a micro it would be seamless.
Done a little more research, seems the Si is a complex device, and its no easy to setup a particular o/p freq.
The clock i/p goes to 2 Pll's, either Pll can be used to clock any of the 3 o/p's on the Si, you can select a multiplication rate for each Pll, then there are 2 dividers for each of the 3 o/p's, so you multiply the clock by a factor, then divide by another and then divide by another.
Works well, but for an application like a function generator with continuously variable o/p frequency the algorithm is going to be tricky.
