NOTES
1.
Input to Output Isolation
: With the use of the Isolink opto-
coupler, we can use the output of the converters to power the
Conner/Winfield 1 MHz clock (output referenced) and the
V
AUX
pin (input referenced) to power the opto-coupler.
2.
Fault Tolerant:
All outputs are capacitively coupled to ensure
that if the master clock stops working the individual units will
continue to operate at their own internal clock frequency,
thereby eliminating a potential single point failure.
3.
Radiated Emissions:
C2 can be added to slow down the clock
edges (Tr and Tf) for reducing radiated emissions.
4.
Table:
The following table shows the capacitor and resis-
tor value to be used for the number of converters to be
synchronized.
