DESCRIPTION
The Silver Telecom Ag1170 is a single
Subscriber Line Interface Circuit (SLIC) in a 14
pin single in line (SIL) or 21 pin dual in line (DIL)
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 Ag1170 has been designed to work with
loop lengths of typically 3.0km (800Ω including
telephone). Its performance to regulatory
standards (G712) allows use in public and
private network applications.

Data Sheet
Ag1170
+5V / +3.3V Low Power Ringing SLIC
FEATURES
• A highly featured low power SLIC in a
14 pin SIL or 21 pin DIL format.
• Integral high efficiency DC/DC
converter. Single +5V or +3.3V supply
voltage.
• Highly integrated with an on-board
ringing generator.
• Tip/Ring polarity reversal. On-Hook
Transmission for caller line ID.
• Line and balance impedance
programmable with external
components (on Ag1170-P version)
• Easy to use, with a minimum number of
external components.
• Simplified protection in “on-premise”
applications.
• Silver Telecom “design-in” assistance.
The Ag1170 has integral dc/dc converter and
ringing generation thus providing all the line
powering requirements from a single supply.
The SLIC requires a minimum of external
components.
The system interface has been designed for
direct connection to popular codecs, for both
audio and signalling
The Ag1170 is ideal for low line count, short
loop length applications, such as ISDN Terminal
Adaptors, Internet Telephony (VoIP), Computer
Telephony Integration (CTI), Wireless Local
Loops (WLL) and Small Office Home Office
(SOHO).

Description
Ring. Connects to the subscriber line Ring.
Tip. Connects to the subscriber line Tip.
Forward/Reverse. A logic 0 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 1 during ringing. Logic 0 for other modes.
Switch Hook. Indicates an off-hook condition when at logic 1.
Line. Connect to ZT2 via impedance programming components.
Line Impedance. Connect to ZT1 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
Audio Out. This is the analog output signal (from Tip and Ring)
to the Codec. Connect via a 100nF capacitor.
Analog Supply. Connected to the +5V or +3.3V supply via an
RC filter, to supply power to the analog circuits.
DC/DC Ground. Ground input for the DC/DC converter.
DC/DC Supply. +5V or +3.3V input for the DC/DC converter.
Power Down of DC/DC Converter. A logic 0 powers off the
PD DC/DC converter. Leave open circuit for free run operation. DO
NOT input logic 1 to this pin.
* Only used for the Ag1170P device. Do not connect for Ag1170 as the impedances are programmed to 600R internally
