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
