Locate the oscillator as close as possible to the microcontroller and remember that the clock line running out of the crystal oscillator is extremely noisy! Don't forget to decouple the supply voltage of crystal oscillator by a 100nF cap, located as close to the supply pins of oscillator as possible.
It's highly recommended to route the clock line over a solid ground plane and to keep the clock line as short as possible. Kai Klaas |
