External Components
The MK2731-04 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.01F should be connected between VDD and GND on pins 3 and 5, and VDD and GND
on pins 10 and 6, as close to the MK2731-04 as possible. Other VDDs can be connected to pin 10. A series
termination resistor of 33
may be used for each clock output. Any unused clock outputs should be left
unconnected (DC, floating). The input crystal must be connected as close to the chip as possible. The input
crystal should be fundamental mode, parallel resonant. For accurate outputs, the crystal should be tuned
with two identical capacitors to ground, as shown on the block diagram. The value of these two crystal caps
should be equal to (CL-6)*2, where CL is the crystal load (or correlation) capacitance.
