When ENS pin is controlled for enable modulation, it is necessary for the stably clock output from CKOUT pin to

wait lock-up time (tLK) .

Note :

In the following cases, it is necessary for the stably clock output from CKOUT pin, to wait lock-up time (tLK) .

- After releasing power-down

- When you change other terminal settings

Output frequency, output clock duty cycle, modulation frequency, and cycle-cycle jitter are not guaranteed

until the output clock is stable. It is recommended to take procedure to release of reset after. lock-up time

(tLK) on the device using the modulation clock or etc.
