External capacitors at each crystal pin to ground are required. They are necessary to tune the open-loop fre-
quency of the internal PLL and to stabilize the frequency in closed-loop operation. The higher the capacitors,
the lower the clock frequency results. The nominal free running frequency should match 18.432 MHz as closely
as possible. Due to different layouts of customer PCBs, the matching capacitor size should be defined in the
application. The suggested values (1.5 pF/3.3 pF) are figures based on experience with various PCB layouts.
