Tool/software:
Hello,
I am trying to generate SYSREF with an LMK04832.
I want to output SYSREF continuously in the same way I did previously with an evaluation board, with a 1.22MHz frequency and 50% duty cycle.
However, with the settings below, SYSREF is only outputting as a 5ns pulse at 2.44MHz. What should I do?
The SYNC is connected to the FPGA but I'm keeping it at a fixed L output. Additionally, I'm configuring the LMK via SPI communication from the FPGA with a 200KHz SCLK, and I can read and write normally.

I found a similar forum thread, but it didn't lead to a solution.
Thanks.
