Pin Description
Pin #
Name
Description
0
IC
Internal Connection.
No pin fitted in this position.
1
TF
Tip Feed.
Connects to external diode to LPGND for protection.
2
IC
Internal Connection
. No pin fitted in this position.
3
VR
Voice Receive
(input) is the 4 wire analog signal to the SLIC.
4
VRef
Voltage Reference
to set the constant current feed to the subscriber line. Constant current
feed can be adjusted by the input voltage on the VRef. This pin can also be grounded for
normal 21mA loop current.
5
VEE
Negative Power Supply voltage.
(-5V).
6
GNDA
Analog Ground.
(0V)
7
GS
Gain setting (Input).
A logic low at this input adds an additional -0.5dB gain in the receive
direction. This gain is in addition to the gain set by the Codec. A high adds 0dB gain.
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 connected via the ring relay to either negative battery feed voltage,
(RV), or ringing voltage input.
12
VDD
Positive Power Supply Voltage.
(+5V)
13
RC
Relay Control (Input).
Active high will apply ringing to the line.
14
RD
Output Drive Sources current when RC is at a logic high.
15
RV
Ring Feed Voltage
connects to pin 11 (RF) through a normally closed relay contact.
16
VRLY
Relay voltage Supply.
(+5V)
17
IC
Internal Connection
. No pin fitted in this position.
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.
