LMK04610: lock time

Xinjian

Part Number: LMK04610

hello,

our application environment need to reconfig output frequency. how long the configrate and lock time?

for example, configrate 10Mhz output, then configrate 11MHz output. my question is how long when we config 11MHz to 11MHz output stable? thanks.

It depends on SPI clock, register written number, PLL2 lock time, most of time is from registers writing.

You can set 0.5 ms as your design target.

Hi, shawn

thanks.

could you support simulation result about lock time? or support simulation software download link?

No such simulation tool now.

For PLL lock time, you can use lock time ~= 4 / LBW.
