Crystal and ceramic resonator oscillators
The ST7 internal clock can be supplied with four different crystal/ ceramic resonator
oscillators. 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 start-up stabilization time. Refer to the crystal/ceramic resonator
manufacturer for more details (frequency, package, accuracy...)
Table 104. Oscillator characteristics
1. The oscillator selection can be optimized in terms of supply current using an high quality resonator with
