I am trying to synchronize the ramps of 2 ADF4159.
As one is called "Master" and output the sync pulse on MUXOUT, the other one, "slave" should be synchronized via de Txdata input.
In open loop configuration, the MUXOUT shows a 2V pulse, it's OK.
When looped back to Txdata, only 0.3V...
There is a mismatch in the interface circuit, and no real information in the datasheet.
So, what is the best way to interconnect the 2 ADF4159?
