I have been following the Jim Miller simple GSDO build project at http://www.jrmiller.demon.co.uk/projects/ministd/frqstd0.htm  I have a  few OCXO's kicking around, but wondering what would the appropriate components be for for  R1,R2, C1, C2 to provide the PLL filter. I assume the PLL filter needs to be designed to accommodate a specific oscillator specifications, or maybe it doesn't really matter and can use the default values in the schematic?. 
Was also considering using a picdiv instead of the 2- 74HC390, not sure if that would be an advantage or disadvantage in terms of operating performance?
