Crystal and ceramic resonator oscillators

The ST7 internal clock can be supplied with ten different Crystal/Ceramic resonator

oscillators. All the information given in this paragraph are 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 start-up stabilization time. Refer to the crystal/ceramic resonator

manufacturer for more details (frequency, package, accuracy...).
