CLOCK AND TIMING CHARACTERISTICS (Cont’d)
13.5.3 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 are based
on characterization results with specified typical
external components. In the application, the reso-
nator and the load capacitors have to be placed as
Figure 71. Typical Application with a Crystal or Ceramic Resonator
Notes:
1. The oscillator selection can be optimized in terms of supply current using an high quality resonator with small R
Refer to crystal/ceramic resonator manufacturer for more details.
