(lock-up time )

The clock stabilization wait time is required when the power is turned on.

If the OE pin is fixed at “H” level, the maximum time after the power is turned on until the required clock is obtained

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

For the stabilization wait time of input clock to the XIN pin, check the characteristics of the resonator or oscillator

used.

OE pin goes “H” level.
