Description
IREF Current Reference.
Connects to an external resistor to provide a high accuracy refer-
ence current. Return path for IREF resistor should be routed to
QGND pin.
TIP Sense.
Analog current input senses dc voltage on TIP side of subscriber
loop.
TIP Transmit Input.
Analog input senses ac voltage on TIP side of subscriber loop.
RING Transmit Input.
Analog input senses ac voltage on RING side of subscriber loop.
RING Sense.
Analog current input senses dc voltage on RING side of sub-
scriber loop.
Negative TIP Current Control.
Analog current output provides dc current return path to V
from TIP side of the loop.
Negative RING Current Control.
Analog current output provides dc current return path to V
from RING side of loop.
Positive TIP Current Control.
Analog current output drives dc current onto TIP side of sub-
scriber loop in normal polarity. Also modulates ac current onto
TIP side of loop.
Power supply for internal analog and digital circuitry. Connect all
VDD pins to the same supply and decouple to adjacent GND pin
as close to the pins as possible.
Ground.
Ground connection for internal analog and digital circuitry. Con-
nect all pins to low-impedance ground plane.
Positive RING Current Control.
Analog current output drives dc current onto RING side of sub-
scriber loop in reverse polarity. Also modulates ac current onto
RING side of loop.
Temperature Sensor.
Senses Internal temperature of Si3200.
Test Relay Driver Output.
Drives test relays for connecting loop test equipment.
No Internal Connection.
Leave unconnected or connect to ground plane.
