FWIW, you will notice that there is a high value resistor shunting the crystal in the 10811. The reason for this is to drain off DC charge caused by cosmic rays hitting the crystal, according to the designers.
DC static tweaks the frequency of an SC-cut crystal somewhat. NIST used this property to create a small rane linear modulator.
