OPERATINGDESCRIPTION
(continued)
The control voltage of the VCO is between 1.33V
and 6V (see Figure 10). The theorical frequency
range of this VCO is in the ratio of 1 to 4.5. The
effective frequency range has to be smaller (1 to
4.2)dueto clampinterventiononfilterlowestvalue.
In order to increase thiseffectivefrequencyrange,
toapossiblerangeof1to6.0onecanaddaresistor
from Pin 6 to Hrefleading.
Thesynchrofrequencymust alwaysbe higherthan
the free running frequency. For example, when
usinga synchrorangebetween31kHzand 96kHz,
thesuggestedfree runningfrequencyis 25kHz.
The PLL1 ensures the coincidence between the
leading edge of the synchro signal and a phase
reference obtained by comparison between the
sawtooth of the VCO and an internal DC voltage
which is I
