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(CL-18), where CL is the
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 33Ω terminating
resistor should be used on the clock output if the trace is longer than 1 inch.
