■ LOCK-UP TIME
When the power down control by the VF pin is valid and the power down is controlled, the desired clock frequency
can be gained once the lock up time tLK has elapsed up to its maximum after the VF pin gets to the H level.
When the modulation control by the VF pin is valid and the modulation is controlled, the frequency set by the
OUT pin output can be set once the lock up time tLK has elapsed up to its maximum after the level for the VF pin
is decided.
Note: The output frequency, the output clock duty cycle, the modulation cycle and the cycle-cycle jitter cannot be
guaranteed until the lock up time has fully elapsed. Therefore, it is recommended to cancel the late reset of
the device or execute other means after the lock up time elapses.
