CLOCKING
The CLOCKING operator generates a square wave output
which period is set by the user. The output is enabled if the
“En” input is set to 1 (TRUE). Clocking has up to 7 inputs to
control output Duty Cycle.
Parameters
Time: The period can be set to between 100 ms and 1098,3
s.
Scale: The user can choose two different scales for the time T
to be set.
• 100 ms...60 s, step 10 ms
• 60,1 s...1098,3 s, step 100 ms
Duty cycle selection: Up to 7 inputs can be selected for 7 different output signal duty cycles.
Depending on the active input, the OUT clock signal has its corresponding duty cycle. EN input
must always be to 1 (TRUE).
Refer to the table below for all possible values of Duty cycle selectable by the user.

➔ The circuit upstream clocking operator must ensure the presence of only one input signal in
addition to enable EN (excluded the pair 10% 80%).
➔ The presence on EN input of high level (TRUE), generates an output signal with a duty cycle = 50%.
