ADF4360-7 generate 350Mhz clock by using 30 nH to drive HMCAD1511 ,HMCAD1511 is work,
oscilloscope can see the 350MHZ clock.
but generate 1.0GH clock by using 3.1nH to drive HMCAD1511,HMCAD1511 is not work ,
oscilloscope can not see the 1.0GHZ clock.
Is it someting different between the two usage scenario?
I think maybe i loss some detail in the ADF4360-7 andHMCAD1511.
please help me.
Thanks a lot!
