CLOCK AND TIMING CHARACTERISTICS (Cont’d)
13.5.4 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 reso-
nator and the load capacitors have to be placed as
