All the information given in this paragraph are based on characterizationresults obtained with typical external components specified in Table 25. In the application,the resonator and the load capacitors have to be placed as close as possible to the oscillatorpins in order to minimize output distortion and startup stabilization time. Refer to the crystalresonator manufacturer for more details on the resonator characteristics (frequency,package, accuracy).Doc ID 022268 Rev 2 67/124
