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 V

source
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...).
