tLK (Lock-up time)

If the XPD pin is fixed at the “H” level, the maximum time after the power is turned on until the set clock signal is

output from CKOUT pin is (the stabilization wait time of input clock to XIN pin) + (the lock-up time “tLK”). For the

input clock stabilization time, check the characteristics of the resonator or oscillator used.
