Device description

6.6.3

High-speed external clock source

The high-speed external (HSE) clock can be generated from the external clock signal or

supplied with a 4 to 32 MHz crystal/ceramic resonator oscillator (see Figure 13).

The external clock signal has to respect the I/O characteristics and follows the

recommended clock input waveform (refer to Figure 12).

Figure 12. HSE clock source timing diagram

Figure 13. Typical application with 8 MHz crystal

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. The REXT value depends on the crystal characteristics (refer to the crystal resonator

manufacturer for more details on them).
