It is my understanding that the RF_EXT_LO_I/O pins can be used to export a divided version of the VCO for debug purposes.
Does the ADRV9008-1 have seperate dividers for the the RF_EXT_LO export and the internal LO used by the receive path?
For instance, lets say that the LO frequency is 2GHz. The ADRV9008-1 synthesiser will be operating at 8GHz and a divide by 4 will be in place to generate 2GHz. Is it possible for me to set the divider on the RF_EXT_LO export to be 2, such that I can export 4GHz?
Graphically, is this configuration possible?
SYNTH(8GHz) ------|DIV 4|---------> 2GHz LO used by the ADRV9008-1 receive path internally
|------------|DIV 2|---------> 4GHz exported out of RF_EXT_LO pins
Thanks for the help!
