Input and Output Voltages
MK3230
Portable System Clock Synthesizer
The MK3230 can operate with VDD = 3.0V to 5.5V, and VDD32 = 2.0V to 5.5V in any combination.
Both VDD pins (pin #5 and pin #13) must be connected to the same voltage.
The amplitude of the 32.768 kHz output clock will be equal to VDD32, and the amplitude of the MHz
clocks will be equal to VDD.
If using a clock input, the input voltage applied to X1 may not exceed VDD32, and the amplitude of any
other input may not exceed VDD. Consult MicroClock if your application is an exception to this.
