■ HANDLING DEVICES
Preventi n g Latch-up
A latch-up can occur if, on this device, (a) a voltage higher than V
input or output pin or (b) a voltage higher than the rating is applied between V
occurs, significantly increases the power supply current and may cause thermal destruction of an element. When
you use this device, be very careful not to exceed the maximum rating.
Handling unused pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, using a pull-up or
pull-down resistor.
Unused output pin should be opened.
The attention when the external clock is used
Input the clock to XIN pin, and XOUT pin should be opened when you use the external clock.
Please pay attention so that an overshoot and an undershoot do not occur to an input clock of XIN pin.
Power supply pins
Please design connecting the power supply pin of this device by as low impedance as possible from the current
supply source.
We recommend connecting electrolyti c capacitor (about 10 µF) and the ceramic capacitor (ab out 0.01 µF) in
parallel between V
SS and VDD pins near the device, as a bypass capacitor.
DD or a voltage lower than VSS is applied to an
DD and VSS pins. The la tc h-up, if it
Oscillation Circuit
Noise near the XIN and XOUT pins may cause the device to malfunction. Design printed circuit boards so that
electric wiring of XIN or XOUT pin and resonator (or ceramic oscillator) do not intersect other wiring.
Design the printed circuit board that surrounds the XIN and XOUT pins with ground.
When changing the pin setting, the stabilization wait time for the modulation clock is required. The stabilization
wait time for the modulation clock takes the maximum value of Lock-Up time in “■ ELECTRICAL CHARACTERISTICS • AC characteristics Lock-Up time”.

If the setting pin is fixed at the “H” or “L” 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 “t

For modulation enable control using the XENS pin during normal operation, the set clock signal is output from
CKOUT pin at most the lock-up time (t

Note : When the pin setting is changed, the CKOUT pin output clock stabilization time is required. Until the output
clock signal becomes stable, the output frequency, output clock duty cycle, modulation period, and cyclecycle jitter cannot be guaranteed. It is therefore advisable to perform processing such as cancelling a reset
of the device at the succeeding stage after the lock-up time.
