25
VPOS
Positive supply inputranging from 5.5V to 15.8V.
34
BGND
Battery Ground, must be shorted with AGND.
27
AGND
Analog Ground, must be shortedwith BGND.
16
ZAC
AC impedance synthesis.
15
ZAC1
RX buffer output, the AC impedance is connected from this node to ZAC.
17
RS
Protection resistors image (the image resistor is connected from this node toZAC).
18
ZB
Balance Network for 2 to 4 wire conversion (the balance impedance ZB is connected from this
node to AGND. ZA impedance is connected from this node to ZAC1).
20
TX
4 wire output port (TXoutput). The signal is referred to AGND. If connected to single supply
CODEC input it must be DC decoupled with proper capacitor.
4 wire input port (RX input); 300K
input impedance. This signal is referred to AGND. If
connected to single supply CODEC output it must be DC decoupled with proper capacitor.
14
RX
19
CAC
AC feedback input, AC/DC split capacitor (CAC).
32
ILTF
Transversal line current image output.
41
TIP
2 wire port; TIP wire (Ia is the current sourced from this pin).
37
RING
2 wire port; RING wire (Ib is the current sunk into this pin).
28
RLIM
Constant current feed programming pin (via RLIM). RLIM should be connected close to this
pin andPCB layout should avoid noise injection on this pin.
30
RTH
Off-hook threshold programming pin (via RTH). RTH should be connected close to this pin
and PCB layout should avoid noise injection on this pin.
29
IREF
Internal bias current setting pin. RREF should be connected close to this pin and PCB layout
should avoid noise injection on this pin.
43
CREV
Reverse polarity transition time control.One proper capacitor connected between this pin and
AGND is setting the reverse polarity transition time. This is the same transition time used to
shape the ”trapezoidal ringing” during ringing injection.
31
RD
DC feedback and ring trip input. RD shouldbe connected closeto this pin and PCB layout
should avoid noise injection on this pin.
