RFSoc ADCs' Clock Phase Adjustment

Jump to solution

Hi,

 

I'm using ZCU111 and I need to adjust when ADCs of two tiles sample data. I have read the documentation [269] but my question still exists. How does MTS achieve synchronization, does it shift the LMX2594's clock phase?  If not, is it possible to adjust the clock phase of a tile? 

In other words, I want ADCs of one tile operate at a clock phase of 20 degrees offset relative to another tile.

 

Thank you in advance for any advice.

Hi @arashr 

To understand the how MTS achieve syncronization , you need to first figure out what are the possible source of latency mismatch across the tiles:

Please refer to the blog below by our expert to understand the MTS procedure
