Ringing Mode. Sets bias conditions during ringing. Must be set
to logic 1 during ringing. Must be set to logic 0 within 500ms of
Ring Trip detect and during normal Off Hook condition.
Audio Out. This is the analog output signal (from Tip and Ring)
to the Codec. Must be ac coupled with typically 100nF.
Balance Impedance. Connect programming components
between ZB and VIN on Ag1460P only.*
Analog Supply. Each pin must be connected to +5VPWR with
10Ω resistors. Decouple each with 100uF (16V) capacitors.
Switch Hook. Indicates Off-Hook when at logic 1. Must be
de-bounced
Terminal Impedance 1. Connect programming components
between ZT1 and ZT2 on Ag1460P only.*
Terminal Impedance 2. Connect programming components
between ZT1 and ZT2 on Ag1460P only.*
Audio In. This is the analog input signal from the Codec (which is
output on Tip and Ring). Must be ac coupled with typically
100nF.
Forward/Reverse. A logic 0 will reverse the Tip and Ring voltage
polarities. F/R is toggled to produce the ringing output.
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.
Loop Off. A logic 1 removes the loop current from the line.
Connect to logic 0 for normal operation.
12, 17, 40, 45 TIP (A) Tip. Connects to the subscriber line Tip.
13, 16, 41, 44 RING (B) Ring. Connects to the subscriber line Ring.
DC-DC Supply. +5V input for the integral DC-DC converter.
14
+5VPWR Decouple to GNDPWR with 220uF (10V) low impedance
capacitor.
15
GNDPWR DC-DC Ground. Internal ground for the DC-DC converter.
42
PD
Power Down. A logic 1 powers off the DC-DC converter.
Connect to logic 0 for normal operation.
43
GNDA Analog Ground. Normally connected to system ground.
*On Ag1460 these pins are used for internal connection, and must be left unconnected.
