External Components
The MK1714 requires a minimum number of external components for proper operation. Decoupling
capacitors of 0.01µF should be connected between VDD and GND (on pins 4 and 7), as close to the chip
as possible. A series termination resistor of 33
connected as close to the chip as possible. The crystal should be a fundamental mode and parallel resonant.
If accurate tuning is required, crystal capacitors should be connected from pins X1 to ground and X2 to
ground. The value of these capacitors is given by the following equation, where C
capacitance: Crystal caps (pF) = (C
should be used. If a clock input is used, drive it into X1 and leave X2 unconnected.
