2. Description
The Silver Telecom Ag1171 is a single Subscriber Line Interface Circuit (SLIC) in a 14 pin
single in line (SIL) format. The combination of features and packaging offers extremely efficient
use of board area, saving significant system size and cost, minimising time to market for
Telephony Systems developers.
The Ag1171 has been designed to work with loop lengths of typically 1.0km (470R including
telephone).
The Ag1171 has integral dc/dc converter and ringing generation thus providing all the line
powering requirements from a single supply. The Ag1171 requires a minimum of external
components, making it ideal for low line count, short loop length applications, such as WLL
Terminal (WLL), Fixed Cellular Terminals (FCT), Fixed Wireless Terminals (FWT) and Internet
Telephony (VoIP).

Description
Ring. Connects to the subscriber line Ring.
Tip. Connects to the subscriber line Tip.
Forward/Reverse. A logic (L) will reverse the Tip and Ring
voltage polarities. F/R is toggled to produce the ringing output.
Ringing Mode. Sets bias conditions during ringing. Must be set
to logic (H) during ringing. Logic (L) for other modes.
Switch Hook. Indicates an off-hook condition when at logic (H).
No Connection. Do not connect to this pin.
No Connection. Do not connect to this pin.
No Connection. Do not connect to this pin.
Audio In. Analog input signal from the Codec (which is output on
Tip and Ring). Connect via a 10nF capacitor
Audio Out. This is the analog output signal (from Tip and Ring)
to the Codec. Connect via a 100nF capacitor.
No Connection. Do not connect to this pin.
DC/DC Ground. Ground input for the DC/DC converter.
DC/DC Supply. +5.0V or +3.3V input for the DC/DC converter.
Power Down DC/DC Converter. A logic (L) on this pin powers
down the Ag1171. DO NOT put logic (H) on this pin.
