But have you made sure that you have extremely short leads to the crystal? Exactly! Like in this example layout: 
Some people don't like to connect the bonding wire of the crystal directly to the solid ground plane, by the way. They make a local ground plane under the crystal, connect the bonding wire to it and connect this local ground plane to the GND pin of micro. Different people, different opinions... And, take the NP0 caps for the burden caps. Are you sure your caps are really 33pF? Kai Klaas |
