High-speed external clock

The high-speed external (HSE) clock can be supplied with a 4 to 16 MHz crystal/ceramic
resonator oscillator. All the information given in this paragraph are based on characterization
results obtained with typical external components specified in

. 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 on the resonator characteristics (frequency,
package, accuracy).

For C

it is recommended to use high-quality ceramic capacitors in the 5 pF to 25pF range (typ.),

designed for high-frequency applications, and selected to match the requirements of the crystal or
resonator. C

are usually the same size. The crystal manufacturer typically specifies a load

capacitance which is the series combination of C

capacitance).

The relatively low value of the RF resistor offers a good protection against issues resulting from use in a
humid environment, due to the induced leakage and the bias condition change. However, it is
recommended to take this point into account if the MCU is used in tough humidity conditions.
