QUAD 5V RINGING SLIC
Name
Description
1, 19, 38, 56
F/R
Forward/Reverse.
A logic 0 will reverse the Tip and Ring voltage
polarities. F/R is toggled to produce the ringing output.
2, 20, 39, 57
TIP (A)
Tip.
Connects to the subscriber line Tip.
3, 21, 40, 58
RING (B)
Ring.
Connects to the subscriber line Ring.
4, 22, 41, 59
LO
Loop Off.
A logic 1 removes the loop current from the line.
Connect to logic 0 for normal operation.
Analog Supply.
Each pin must be connected to +5V
PWR
with
10
resistors. Decouple each with 100uF (16V) capacitors.
No Connection.
These pins are not connected internally to the
device.
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.
Analog Ground.
Normally connected to system ground. All 4
pins must be connected to analog ground by separate tracks or
ground plane.
Audio Out.
This is the analog output signal (from Tip and Ring)
to the Codec. Must be ac coupled with typically 100nF.
Switch Hook.
Indicates Off-Hook when at logic 1. Must be
de-bounced
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.
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.
Terminal Impedance 1.
Connect programming components
between ZT
1
and ZT
2
on Ag1460P only.*
Terminal Impedance 2.
Connect programming components
between ZT
1
and ZT
2
on Ag1460P only.*
Balance Impedance.
Connect programming components
between ZB and V
IN
on Ag1460P only.*
DC-DC Supply.
+5V input for the integral DC-DC converter.
Decouple to GNDPWR with 220uF (10V) low impedance
capacitor.
Power Down.
A logic 1 powers off the DC-DC converter.
Connect to logic 0 for normal operation.
