The MK1574-01A/B requires a minimum number of external components for proper operation. An RC network (see
the section “Loop Bandwidth and Loop Filter Component Selection”) should be connected between CAP1 and
CAP2 as close tot he device as possible. Decoupling capacitors of 0.01µF should be connected between VDD and
GND on pins 2, 3, 5 and 7, as close to the device as possible. A series termination resistor of 33 may be used
close to each clock output pin to reduce reflections.
