LMK04826 / about holdover

Hi,

Customer would like to know about holdover.

Could holdover setting for pin select mode take the place of holdover force mode 0x14[3] ?

Best Regards,

Kato

  • Hi Kato-san,

    Using the pin select mode to enter holdover is similar to Holdover Force but not the exact same. When the device is in holdover due to the pin select mode, exit from holdover caused by a chance in the pin select mode will only occur when the newly selected reference is phase aligned with PLL1 feedback path. Holdover force is not subject to these criteria.
