Tool/software:
I use LMK04832 as a PLL, I want to use the holdover function. I set HOLDOVER_EN=1 , EXIT based on DLD=1 , HOLDOVER_PLL1_DETECT=1, TRACK_EN=1. the CLK input is clk0. when power on the pll is locked
when I remove the clk0 input, but i found the holdoer don't work. if other register need set?
Hello Ye,
I believe you're using PLL1 correct?
Please note exit based on DLD can take some time as holdover will be enabled and will wait for alignment of PLL1 R & N divider before exiting holdover.
Sounds like from your settings your attempting the following:
Please follow steps above for tracked CPout1 holdover.
Best regards,
Vicente
