Electrical Specifications
External Components
The MK2754 requires a minimum number of external components for proper operation. A decoupling
capacitor of 0.1µF should be connected between VDD and GND on pins 2 and 4, as close to the MK2754
as possible. A series termination resistor of 33 may be used for the clock output. The input crystal must be
connected as close to the chip as possible. The input crystal should be a parallel mode, pullable, AT cut,
13.5MHz, with 14pF load capacitance. Consult MicroClock for recommended suppliers. IMPORTANT -
read application note MAN05 before laying out the PCB.
