Loop Closure Detector Output
—Ring Trip Detector Output.
When
low, this logic output indicates that an off-hook condition exists or ring-
ing is tripped.
No Connection.
There is no internal connection to this pin.
Transmit ac Output Voltage.
Output of internal AAC amplifier. This
output is a voltage that is directly proportional to the differential ac tip/
ring current.
Receive ac Signal Input (Noninverting).
This high-impedance input
controls to ac differential voltage on tip and ring. This node is a floating
input.
Receive ac Signal Input (Inverting).
This high-impedance input con-
trols to ac differential voltage on tip and ring. This node is a floating
input.
dc Output Voltage.
This output is a voltage that is directly propor-
tional to the absolute value of the differential tip/ring current. This is
used to set the dc current limit and the ring trip threshold.
Current-Limit Program Input.
A resistor is connected from this pin to
DCOUT to program the dc current limit for the device.
Filter Capacitor.
Connect a capacitor from this node to ground.
Filter Capacitor.
Connect a capacitor from this node to CF2.
Ring Trip Filter.
Connect this lead to DCOUT via a resistor and to
AGND with a capacitor or a resistor capacitor combination, depending
on the ringing type, to filter the ring trip circuit to prevent spurious
responses.
SLIC Internal Reference Current.
Connect a resistor between this
pin and AGND to generate an internal reference current.
Analog Signal Ground.
Analog Power Supply.
User choice of 5 V or 3.3 V nominal power
supply.
Battery Supply 1.
High-voltage battery.
Battery Supply 2.
Low-voltage battery or power control resistor.
Battery Ground.
Ground return for the battery supplies.
