10.3.3 External clock sources and timing characteristics

HSE external clock

An HSE clock can be generated by feeding an external clock signal of up to 24 MHz to the

OSCIN pin.

Clock characteristics are subject to general operating conditions for VDD and TA.

HSE crystal/ceramic resonator oscillator

The HSE clock can be supplied using a crystal/ceramic resonator oscillator of up to 24 MHz.

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 startup stabilization time. Refer to the crystal resonator manufacturer for more details

(frequency, package, accuracy...).
