Pin Description
Pin #
Name
Description
1
TF
Tip Feed.
Connects to external diode for protection.
2
LPGND
Loop Ground
. is the system ground reference with respect to VBat. Normally tied with
AGND.
3
VR
Voice Receive
(input)
is the 4 wire analog signal to the SLIC.
4
V
Ref
Voltage Reference (Input)
to set the constant current feed to the subscriber line. Constant
current feed can be adjusted by the input voltage on the V
Ref
. This pin can also be
grounded for normal 25 mA loop current.
5
VEE
Negative Power Supply Voltage
(-5V).
6
AGND
Analog Ground (0V
).
7
PD
Power Denial (Input)
. A logic high will isolate the battery voltage to Tip/Ring.
8
VX
Voice Transmit (Output)
is the 4-wire analog signal from the SLIC.
9
TIP
Connects to the “Tip” lead
of the telephone line .
10
RING
Connects to the “Ring” lead of
the telephone line
11
RF
Ring Feed (Input)
is normally connected to Ring relay for negative battery feed voltage
and ringing voltage input.
12
VDD
Positive Power Supply Voltage (+5V).
13
RC
Relay Control
(Input)
. Active high.
14
RD
Open collector sinks current when RC is at logic high.
15
RV
Ring Feed Voltage
connects to pin 11 (RF) through a normally closed relay.
16
VRLY
Relay voltage Supply (+5V).
17
CD
Clamping Diode
. Connects to GNDA.
18
VBat
Negative Battery Feed Supply Voltage (-48V).
19
CAP
Connects external capacitor to ground for ring trip.
20
SHK
Switch Hook Detect (Output).
Active high.
