High-speed external clock generated from a crystal/ceramic resonator  
The high-speed external (HSE) clock can be supplied with a 4 to 16 MHz crystal/ceramic  
resonator oscillator. All the information given in this paragraph are based on characterization  
results obtained with typical external components specified in Table 22. In the application,  
the resonator and the load capacitors have to be placed as close as possible to the oscillator  
pins in order to minimize output distortion and startup stabilization time. Refer to the crystal  
resonator manufacturer for more details on the resonator characteristics (frequency,  
package, accuracy).
