EIA/ITU PABX SLIC with 30mA Loop Feed
Features
The Intersil SLIC incorporates many of the BORSHT
functions on a single IC chip. This includes DC battery feed,
a ring relay driver, supervisory and hybrid functions. This
device is designed to maintain transmission performance in
the presence of externally induced longitudinal currents.
Using the unique Intersil dielectric isolation process, the
SLIC can operate directly with a wide range of station battery
voltages.
• Capable of 12V or 5V (VB+) Operation
The SLIC also provides selective denial of power. If the PBX
system becomes overloaded during an emergency, the SLIC
will provide system protection by denying power to selected
subscriber loops.
The Intersil SLIC is ideally suited for the design of new digital
PBX systems, by eliminating bulky hybrid transformers.

DESCRIPTION

1
TIP
An analog input connected to the TIP (more positive) side of the subscriber loop through a 150Ω feed
resistor and a ring relay contact. Functions with the Ring terminal to receive voice signals from the
telephone and for loop monitoring process.
3
2
RING
An analog input connected to the RING (more negative) side of the subscriber loop through a 150Ω
feed resistor and a ring relay contact. Functions with the Tip terminal to receive voice signals from
the telephone and for loop monitoring purposes.

3
VB+
5
4
C1
Capacitor #1 - Optional Capacitor used to improve power supply rejection. This pin should be left open if
unused.
6
5
C3
Capacitor #3 - An external capacitor to be connected between this terminal and analog ground.
Required for proper operation of the loop current limiting function, and for filtering VB- supply. Typical
value is 0.3µF, 30V.
7
6
DG
(Note 5)
Digital Ground - To be connected to zero potential and serves as a reference for all digital inputs and
outputs on the SLIC.
9
7
RS
Ring Synchronization Input - A TTL - compatible clock input. The clock should be arranged such that
a positive transition occurs on the negative going zero crossing of the ring voltage source, ensuring
that the ring relay is activated and deactivated when the instantaneous ring voltage is near zero. If
synchronization is not required, tie to 5V.
10
8
RD
Relay Driver - A low active open collector logic output. When enabled, the external ring relay is
energized.
11
9
TF
Tip Feed - A low impedance analog output connected to the TIP terminal through a 150Ω feed
resistor. Functions with the RF terminal to provide loop current, feed voice signals to the telephone
set, and sink longitudinal current.
12
10
RF
Ring Feed - A low impedance analog output connected to the RING terminal through a 150Ω feed
resistor. Functions with the TF terminal to provide loop current, feed voice signal to the telephone
set, and sink longitudinal current.
13
11
VB-
Negative Voltage Source - Most negative supply. VB- is typically -48V with an operational range of 42V to -58V. Frequently referred to as “battery”.
14
12
BG
(Note 1)
Battery Ground - To be connected to zero potential. All loop current and some quiescent current
flows into this ground terminal.
16
13
SHD
Switch Hook Detection - A low active LS TTL - compatible logic output. This output is enabled for
loop currents exceeding 10mA and disabled for loop currents less than 5mA.
17
14
GKD
Ground Key Detection - A low active LS TTL - compatible logic output. This output is enabled if the
DC current into the ring lead exceeds the DC current out of the tip lead by more than 20mA, and
disabled if this current difference is less than 10mA.
18
15
PD
Power Denial - A low active TTL - Compatible logic input. When enabled the switch hook detect
(SHD) and ground key detect (GKD) are not necessarily valid, and the relay driver (RD) output is
disabled.
19
16
RC
Ring Command - A low active TTL - Compatible logic input. When enabled, the relay driver (RD)
output goes low on the next rising edge of the ring sync (RS) input, as long as the SLIC is not in the
power denial state (PD = 0) or the subscriber is not already off- hook (SHD = 0).
20
17
C2
Capacitor #2 - An external capacitor to be connected between this terminal and digital ground.
Prevents false ground key indications from occurring during ring trip detection. Typical value is
0.15µF, 10V. This capacitor is not used if ground key function is not required.

SYMBOL
DESCRIPTION
25
21
RX
Receive Input, 4-Wire Side - A high impedance analog input which is internally biased. Capacitive
coupling to this input is required. AC signals appearing at this input differentially drive the Tip feed
and Ring feed amplifiers, which in turn drive tip and ring through 300Ω of feed resistance on each
side of the line.
26
22
C4
Capacitor #4 - An external capacitor to be connected between this terminal and analog ground. This
capacitor prevents false ground key indication and false ring trip detection from occurring when
longitudinal currents are induced onto the subscriber loop from nearby power lines and other noise
sources. This capacitor is also required for the proper operation of ring trip detection. Typical value
is 0.5µF to 1.0µF, 20V. This capacitor should be nonpolarized.
27
23
AG
(Note 5)
Analog Ground - To be connected to zero potential and serves as a reference for the transmit output
(TX) and receive input (RX) terminals.
28
24
TX
Transmit Output, 4-Wire Side - A low impedance analog output which represents the differential
voltage across Tip and Ring. Transhybrid balancing must be performed (using the SLIC
microcircuit’s spare op amp) beyond this output to completely implement two to four wire conversion.
This output is unbalanced and referenced to analog ground. Since the DC level of this output varies
with loop current, capacitive coupling to the next stage is essential.
NC
No internal connection.
1, 8, 5, 22
NOTE:
5. All grounds (AG, BG, and DG) must be applied before VB+ or VB-. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.

FIGURE 1. TYPICAL LINE CIRCUIT APPLICATION WITH THE MONOLITHIC SLIC
Typical Component Values
C1 = 0.5µF (Note 6).
R1 = R2 = R3 = 100kΩ (0.1% Match Required, 1% absolute
value), ZB = 0 for 600Ω Terminations (Note 7).
C2 = 0.15µF, 10V.
RB1 = RB2 = RB3 = RB4 = 150Ω (0.1% Match Required, 1%
absolute value).
C3 = 0.3µF, 30V.
C4 = 0.5µF to 1.0µF, 10%, 20V (Should be nonpolarized).
C5 = 0.5µF, 20V.
C6 = C7 = 0.5µF (10% Match Required) (Note 7), 20V.
C8 = 0.01µF, 100V.
RS = 1kΩ, CS = 0.1µF, 200V typically, depending on VRING
and line length.
Z1 = 150V to 200V transient protection. PTC used as ring
generator ballast.
C9 = 0.01µF, 20V, ±20%.
NOTES:
6. C1 is an optional capacitor used to improve VB+ supply rejection. This pin must be left open if unused.
7. To obtain the specified transhybrid loss it is necessary for the three legs of the balance network, C6-R1 and R2 and C7-ZB-R3, to match in
impedance to within 0.3%. Thus, if C6 and C7 are 1µF each, a 20% match is adequate. It should be noted that the transmit output to C6 sees
a -22V step when the loop is closed. Too large a value for C6 may produce an excessively long transient at the op amp output to the PCM
Filter/CODEC.
A 0.5µF and 100kΩ gives a time constant of 50ms. The uncommitted op amp output is internally clamped to stay within ±6.6V and is current
limited.
8. Secondary protection diode bridge recommended is a 2A, 200V type.
9. All grounds (AG, BG, and DG) must be applied before VB+ or VB-. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
10. Pin numbers given for DIP package.
