we are using LM97593 for RF sensor application. in this regard there are 2 seperate units each having LM97593.
These two units having seperate gps receiver that provides reference time &clock . To achieve the synchronization between 2 units DDC'S we are deriving SI bar with reference to GPStime. BUt GPS tme offset between two units is 50ns.
the problem here is while collecting the data from 2 units it is giving different delays each time,though input signal source( signal generator) is common to both units. here my doubt is which causes the output of 2 units phase variation and delay. some times both outputs are out of phase ,some times aligning and some times below 90 degrees.
