SNAS699B January 2017 – July 2019 LMK04610
PRODUCTION DATA.
During the initial programming, the LMK0461x can be configured to start-up into holdover. It presets the VCXO Control voltage to approximately 1.2 V. This allows PLL2 to lock to the VCXO reference. PLL1 locks as soon a valid reference input clock is detected. The holdover status can be optionally displayed at the status pins.
