External clock sources and timing characteristics
HSE user external clock
Subject to general operating conditions for V
Table 30.
1. In CSS is used, the external clock must have a frequency above 500 kHz.
Figure 16. HSE external clock source
HSE crystal/ceramic resonator oscillator
The HSE clock can be supplied using a crystal/ceramic resonator oscillator of up to 16 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...).
