HSE crystal/ceramic resonator oscillator

The HSE clock can be supplied with a 1 to 16 MHz crystal/ceramic resonator oscillator. All

the information given in this paragraph is based on characterization results with specified

typical external components. 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 start-up stabilization time. Refer to the crystal resonator manufacturer for more details

(frequency, package, accuracy...).
