External Components
The MK3234 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.1F should be connected between VDD and GND, and VDD32 and GND, as close to the
MK3234 as possible. A series resistor of 10k
should be used on the VDD32 supply. A series termination
resistor of 33
may be used for each clock output, except the 32.768 kHz. For tuning the real time clock
output, use a 32.768 kHz crystal with a load capacitance of 12.5pF, and connect a 20pF±5% (NPO
dielectric) capacitor between each crystal pin and ground. The 32.768 kHz crystal must be connected as
close to the chip as possible. The 14.3 MHz output is not suitable for driving CRT displays. A separate
14.318 MHz crystal should be used at the input to the graphics controller chip. Consult MicroClock for a
recommended external circuit schematic.
Frequency transitions will occur smoothly.
