We changed the registers on LMK04828 on the RFSoC4x2 board using the TICS PRO app. Now we want to revert back to the original clock file (.tcs). Could you please provide us the original hex values or .tcs file for RFSoC4x2 board? Thank you for your help.

Also,  
The file on GitHub ([RFSoC-MTS/boards/RFSoC4x2/xrfclk/LMK04828\_500.0.txt at main · Xilinx/RFSoC-MTS · GitHub](https://github.com/Xilinx/RFSoC-MTS/blob/main/boards/RFSoC4x2/xrfclk/LMK04828_500.0.txt)) doesn’t match with the clocking diagram on the RFSoC4x2 data sheet ([https://www.realdigital.org/downloads/15456c97a4fe5a1ee66208c5aa3894bb.pdf](https://www.realdigital.org/downloads/15456c97a4fe5a1ee66208c5aa3894bb.pdf)). Please see the attachments. Can you confirm this is the correct file or provide us with the right one?

Thank you and have a great day.
