Hi Joe,
Yes, but we came from a situation where we had an X-Tal oscillator for nr2, and
the idea was: replace it with a chip and save a lot of board space an discreet
components. On the other hand this might solve the crosstalk problem.
Are we going to place a lot discrete components on that small SMD board, or
will we put them on the motherboard and only use the smd board for osc 1 and 3.

Oscillator #2 doesn't have to be variable, or even very accurate. A simple
crystal oscillator will do and you can still do passband tuning. I suggest
this because the Si5351 will probably have horrible crosstalk spurious if all
3 oscillators are running. It's much better if you just run #0 and #2 and keep
the output traces well isolated from each other. In the. Si570 approach, this
eliminates an expensive 3rd part.

Hello Ashhar,
I had some exchange of idears about SMD and modules, so here a new version
with a new drawing, the old .gif is also used in this temp.htm text.
