Capacitively-coupling the Receive Section(s) of the XRT82D20 to the line
Capacitive coupling provides a lower cost interface to the line. It must be noted that the line isolation is limited
to the breakdown voltage of the capactior versus the typical transformer isolation of 1,500 to 3,000 volts. With
a capacitor there is also no DC isolation to ground as there is with with a transformer.
Applications that are not sensitive to these issues can benefit from the lower cost approach of using capacitor
coupling on the receive input.
the recommended schematics for capacitively
coupling the receiver to the line.
NOTE: Resistive divider attenuates the input signal by one-half for both 75
and 120 applications.
