Pin Description - DIL Package
Pin #
Name
Description
1
TIP (A)
Tip.
Connects to the subscriber line Tip.
2
RING (B)
Ring.
Connects to the subscriber line Ring.
3
IC
Internal Connection.
Do not connect externally to this pin.
4
PD
Power Down of DC/DC Converter
. A logic 0 powers off the
DC/DC converter. Leave open circuit for free run operation. DO
NOT input logic 1 to this pin.
5
NC
No Connection.
This pin is not connected internally.
6
NC
No Connection.
This pin is not connected internally.
7
RM
Ringing Mode.
Sets bias conditions during ringing. Must be set
to logic 1 during ringing. Logic 0 for other modes.
8
GND
A
Analog Ground.
Normally connected to system ground.
9
+V
A
Analog Supply.
Connect to the +5V or +3.3V supply via an RC
filter, to supply power to the analog circuits.
Line Impedance.
Connect to ZT1 via impedance programming
components.
Line Impedance.
Connect to ZT2 via impedance programming
components.
Balance Impedance.
Connect to VIN via impedance
programming components.
Audio In.
Analog input signal from the Codec (which is output on
Tip and Ring). Connect via a 100nF capacitor.

13
V
IN
14
NC
No Connection.
This pin is not connected internally.
15
V
OUT
Audio Out.
Analog output signal (from Tip and Ring) to the
Codec. Connect via a 100nF capacitor.
Forward/Reverse.
A logic 0 will reverse the Tip and Ring voltage
polarities. F/R is toggled to produce the ringing output.
16
F/R
17
SHK
Switch Hook.
Indicates an off-hook condition when at logic 1.
18
GND
PWR
DC/DC Ground.
Ground input for the DC/DC converter.
19
+V
PWR
DC/DC Supply.
+5V or +3.3V input for the DC/DC converter.
20
GND
PWR
DC/DC Ground.
Ground input for the DC/DC converter.
21
+V
PWR
DC/DC Supply.
+5V or +3.3V input for the DC/DC converter.
* Only used for the Ag1170P device. Do not connect for Ag1170 as impedance is programmed to 600R internally
