CLOCK AND TIMING CHARACTERISTICS (Cont’d)
11.5.3 Crystal and Ceramic Resonator Oscillators
The ST6 internal clock can be supplied with sever-
al different Crystal/Ceramic resonator oscillators.
Only parallel resonant crystals can be used. All the
information given in this paragraph are based on
Notes:
1. Resonator characteristics given by the crystal/ceramic resonator manufacturer.
2. t
3. The oscillator selection can be optimized in terms of supply current using an high quality resonator with small R
