Description
1
TIP (A)
Tip.
Connects to the subscriber line Tip.
2
RING (B)
Ring.
Connects to the subscriber line Ring.
3
NC
No Connection.
This pin is not connected internally to the
device.
Power Down.
A logic 1 powers off the DC-DC converter.
Connect to logic 0 for normal operation.
No Connection.
This pin is not connected internally to the
device.
Loop Off.
A logic 1 removes the loop current from the line.
Connect to logic 0 for normal operation.
Ringing Mode.
Sets bias conditions during ringing. Must be set
to logic 1 during ringing.

A
Analog Ground.
Normally connected to system ground.
9
+5V
A
Analog Supply.
This pin must be connected to the +5V supply
via an RC filter, to supply power to the analog circuits.
No Connection.
This pin is not connected internally to the
device.
No Connection.
This pin is not connected internally to the
device.
No Connection.
This pin is not connected internally to the
device.
Audio In.
This is the analog input signal from the Codec (which is
output on Tip and Ring). Connected via a 100nF capacitor.
Slew Rate Capacitor.
A capacitor is fitted between this pin and
GND to control the battery reversal and the ringing slew rate.
220nF is recommended.
Audio Out.
This is the analog output signal (from Tip and Ring)
to the Codec. Connected 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.
