CPC5710N
With the application circuit in
capacitors serve to reduce the magnitude of the
high-amplitude, low-frequency ringing signals, while
making the ringing detection threshold of the
CPC5710N variable with the frequency of the ringing
signal. With the circuit as given, CMPOUT will change
states with a 15Hz ringing signal at approximately
48V
change states with a ringing signal amplitude of
approximately 11.5V
In applications where CPC5710N will be used only as
a ringing level detector, or if significant attenuation of
the amplified signal can be tolerated, the frequency
variability of the ringing detection threshold can be
reduced by increasing the value of the resistors and
capacitors in series with the input.

2.4 Power Quality
CPC5710N works best with a clean power supply. To
clean up power supply noise, Clare, Inc., recommends
using a pi network on the V
