CLOCK AND TIMING CHARACTERISTICS
(Cont’d)
14.4.3 Crystal Resonator Oscillators
The ST7 internal clock is supplied with one Crystal
resonator oscillator. All the information given in
this paragraph are based on characterization re-
sults with specified typical external componants. In
the application, the resonator and the load capaci-
tors 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
resonator manufacturer for more details (frequen-
cy, package, accuracy...).
Figure 39. Typical Application with a Crystal Resonator
Notes:
1. Resonator characteristics given by the crystal resonator manufacturer.
2.
t
is the typical oscillator start-up time measured between V
DD
=2.8V and the fetch of the first instruction (with a
quick V
DD
ramp-up from 0 to 5V (<50
μ
s).
3. The oscillator selection can be optimized in terms of supply current using an high quality resonator with small R
S
value.
Refer to crystal resonator manufacturer for more details.
