The PureEdge™ nomenclature is slightly different than the traditional 3rd overtone or SAW-based crystal oscillator. Silicon provides flexibility, and this must be reflected in the nomenclature. Currently there are single and dual frequency XO and VCXO devices in production. The second and third place in the name is dedicated for product family. There are 2.5 and 3.3 V differential interfaces available in both 10,000 and 100 piece rails.
