Using the AD9517-3 tuned to 2.0GHz

Hi All,

 

I would like to use the AD9517-3 with a 10MHz input clock, tune the VCO to 2.0GHz and drive the LVPECL outputs at 2.0GHz.

 

I realize that the datasheet limits the LVPECL to 1.6GHz when the output is created from the VCO.  However, is this something

that is still do-able?  (i.e. with reduced output amplitude or perhaps by hand-selecting parts)

 

Also, I could not find a clock generator chip that would allow LVPECL outputs to get up to 2.0GHz when running the those

outputs from an internal PLL/VCO.  Are there any devices in the works that anyone knows of that could have that capability?

 

Thanks!
