External Components/Crystal Selection
A minimum number of external components are required for proper oscillation. For a crystal input, a
parallel resonant 14.31818 MHz, 18pF load, crystal is recommended. Do not use a crystal with lower load
capacitance. It is possible to use a crystal with higher load capacitance. In this case, external capacitors must
be connected from each of X1 and X2 to ground. The value of these caps equals 2(C
crystal load capacitance in pF. So for a 20 pF crystal, use 4 pF caps. The frequency tolerance of the crystal
should be 30ppm or better. For a clock input, connect to X1 and leave X2 unconnected. A decoupling
capacitor of 0.1µF should be connected between VDD and GND on pins 2 and 3, and a 33 terminating
resistor should be used on the clock output if the trace is longer than 1 inch.
