External capacitors at each crystal pin to ground are required. 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 sug-
gested values (1.5 pF/3.3 pF) are figures based on experience with various PCB layouts.
“n” means “1” or “2”, “s” means “L” or “R”
