For a new project, I want to explore the possibility of using your LMK5C33216 device as a SYSREF and reference clock generetor for radio modules.
I need to make a synchronization network between 4 modules connected on paths that are due to a previous implementation (old backplane) , so I can't make a star clock distribution path.
Two main requirements must be met:
1) The system must guarantee phase coherence at each restart (or rather, all the outputs must restart with a known phase between the modules outputs).
I plan to do this feature using ZDM with a 3.84MHz SYSREF signal between modules).
Using the configuration shown in the attached diagram, do you think it is possible to obtain phase certainty between the modules which is comparable to the output skew between a single LMK5C33216 device?
2) The main device (MODULE 1, system primary clock source) must be able to tune the frequency of all the system outputs (4 modules) by acting on its own DCO.
Do you think there are any impediments?
