Description
Two wire unbalanced output carryng out the following signals reduced by 40:
1) DC voltage to perform the proper DC characteristic.
2) Ringing Signal
3) Voice Signal
AC line Impedance Adjustment ProtectionResistances Compensation
Transmit Amplifier Output
Comparator Input. This is the input comparator that senses the line voltage in power down and in
automatic stand-by, allowing off hook detection in this mode.
Aut. Input. It is a part of the digital interface. Loaded when CS is low.
Master Reset Input. When it is connected to ground the SLIC is forced inpower down. It has an
internalpull-up. (typ. 200K
) (*)
Power on/power off input.This input ispart of digital interface.Loaded when CS is low.
Ring Enable Input. This input is part of the digital interface.Loaded when CS is low.
Chip Select Input.
Ground Key Output Enabled by CS Low.
On Hook/off Hook OutputEnabled by CS Low.
State control Signal 2.
State Control Signal 1. Combination of C1 and C2 define operating mode of the high voltage part.
Low Level Ringing Signal Input.

AC - DC Feedback Input.
Positive Supply Voltage, +5V.
Bias Setting Pin.
Negative Supply Voltage, -5V.
Analog and Digital Ground.
Limiting Current Selection Input. Loaded when CS is low.
Power Down Output. Driving the high voltage part L3000N through the bias resistor RH.
TX Amplifier Negative Input performig the two to four wire conversion. In case of application with
2nd Generation COMBO performing also the echocancellation (ex TS5070/5071), this pinmust
be connected to GND.
AC Feedback Input.
