■ PIN SETTING

The modulation clock requires stabilization wait time after the PIN setting is changed. For the modulation clock

stabilization wait time, assure the maximum value for “Lock-up time” in the AC Characteristics list in

“

■ ELECTRICAL CHARACTERISTICS”.

ENS modulation enable setting

Note : Spectrum does not diffuse when “L” is set to ENS pin.

MB88155-xx2, xx3 do not have ENS pin.

XPD power down

Note : When setting “L” to XPD pin, it becomes power down mode (low power consumption mode) .

Both CKOUT and REFOUT of output pins are fixed to “L” output during power down.

MB88155-xx0, xx1 do not have XPD pin.

SEL modulation rate setting

Note : The modulation rate can be changed at the level of the pin.
