LTC2325 [Copy link]

 

According to your previous post, the sync signal is input at 10MHz, output at 10MHz, and then the phase and duty cycle are multiplied by 2. It seems that there is a big error. I don't know if my configuration is correct.

I remember that this worked well. I just checked it and it was the same as yours, showing 0. Then I switched from MMCL to PLL and back again and it changed back. [attach]623692[/attach] [attach]623691[/attach]   Details Published on 2022-7-19 19:15

I'm a little confused about the terms sync and sync_out. Does sync generate sync_out or does sync_out generate sync?  Details Published on 2021-12-1 14:08

Because it has been a long time, I forgot how the module was implemented, so I wrote a simulation file to see the result. The timing is the result of the bottom picture. Inputting a 10MHz signal will output the same timing as sync_out.  Details Published on 2021-12-1 14:49

First, the 110M clock PLL generates a 10MHz clock, right? Then 10MHz is used as input to generate clk_out_10_sync, and then clk_out_10_sync is used as input to output sync.  Details Published on 2021-12-1 16:19

, then clk_out_10_sync is used as input and then output sync

This is the order, right?

You said it was generated by 10M clock, but your timing diagram is obviously not 10M.

Your cycle is 5ns
