■ PIN SETTING

When changing the pin setting, the stabilization wait time for the modulation clock required. The stabilization

wait time for the modulation clock takes the maximum value of Lock-Up time in “

• AC Characteristics”.

ENS modulation enable setting

Note : Spectrum does not spread when “L” is set to ENS. The clock with low jitter can be obtained.

FREQ0, FREQ1 frequency setting

Note : It is set according to the frequency of the clock input to the device. Set FREQ0 pin to “H” for the pin opened

because FREQ0 pin has pull-up resistor.

XPD power down setting

Note : When “L” is set to XPD pin, the power down operation is implemented and “L” is output to CKOUT pin. When

“H” is input to XPD pin or XPD pin is opened, normal operation is implemented because the XPD pin has

pull-up resistor.
