Figure 2 - Pin Connections
Pin Description
Pin#
Name
Description
1
TIP
Tip Lead.
Connects to the "Tip" or "A" lead of subscriber line.
2
RING
Ring Lead
. Connects to the "Ring" or "B" lead of subscriber line.
3
IC
Internal Connection.
This pin is internally connected and must be left open circuit.
4
DCRI
DC Ringing Voltage Input.
A continuous DC voltage is applied to this pin. This
voltage is the positive supply rail for the internal ringing amplifier.
5
LPGND
Battery Ground.
V
BAT
return path for subscriber line. Connects to the system energy
dumping ground. LPGND and AGND must be connected together within the system.
6
VBAT
Battery Voltage.
Battery supply feed for subscriber line. Typically -48V DC is applied
to this pin.
7
IC
I
nternal Connection.
This pin is internally connected and must be left open circuit.
8
VDD
Positive Supply Voltage.
+5V DC supply rail. VDD must not be applied before VEE is
applied.
9
AGND
Analogue Ground.
V
DD
and V
EE
return path. AGND and LPGND must be connected
together within the system.
10
VEE
Negative Supply Voltage.
-5V DC supply rail. VDD must not be applied before VEE is
applied.
11
RC
Ringing Control.
A logic 1 enables a balanced ringing voltage to be applied to the
subscriber line when the correct Ringing Voltage input is applied.
12
PD
Power Denial.
A logic 1 will isolate the battery voltage from Tip and Ring.
13
IC
Internal Connection.
This pin is internally connected and must be left open circuit.
14
SHK
Switch Hook Detect.
A logic 1 indicates when the subscriber line has gone off-hook.
15
VR
Receive Signal (input).
This is the analogue signal to the subscriber’s set.
16
VREF
Reference Voltage.
A DC reference voltage is applied to this pin to set the constant
current feed to subscriber line. This pin may also be grounded for normal 25mA loop
current when V
BAT
= -48V.
