LMX2694EPEVM: Synchronizing Two LMX2694EPEVM

Part Number: LMX2694EPEVM


Hi, I have a question regarding LMX2694EPEVM 15-GHz wideband RF synthesizer evaluation module.

My main goal is to get two clock signals with a frequency of 180 MHz and I use a single Wenzel MRO 200MHz as shown below. If I divide the output of the MRO to 2 and supply these two signals to 2 different LMX2694EPEVM, how can I synchronize the outputs? Where can I supply a reference clock such as 10MHz to synchronize them?

  • Hi Onur,

    If the sync category is Cat.2, you can simply use TICS Pro to provide a sync pulse to the EVMs. 

    If it is a Cat.3 sync, your setup would not work. You have to use a clock device to generate the ref clocks and the sync pulses to the EVMs. 

    There is an example in here.

    Another useful appnote here.
