LMK04828: Input Clock Switching and PLL1 Lock Status

Part Number: LMK04828

Hello,

My customer has a question about LMK04828.

[Q]
Is it appropriate for Lock Status of PLL1 to become Unlock once when input switching is performed under the following conditions?

<conditions>
- CLKin1 = 122.88MHz
- CLKin0 = 122.88MHz
- The phase difference between the two inputs is 0 ns.
- Input Clock Switching = Manual Mode

Although the Lock Status of PLL1 becomes unlock at the time of switching input, it is not a problem in particular.
I would be happy to tell you if you have any comments.

Best Regards, 

Kaede Kudo
