Design Equations
Refer to Figure 14 for programming resistor connections.
Loop Supervision Thresholds
SWITCH HOOK DETECT
The desired switch hook detect threshold current (ISH) is set by
a single external resistor, RSH as follows
The loop current threshold programming range is from 5mA
to 15mA.
RING TRIP DETECT
The ring trip detect threshold (IRT) is set by a single external
resistor, RRT as follows.
IRT should be set between the peak ringing current and the
peak off hook current while still ringing. In addition, the ring
trip current must be set below the transient current limit
including tolerances. The ringing signal filter capacitor CRT,
in parallel with RRT sets the ring trip response time.
LOOP CURRENT LIMIT
The DC loop current limit (ILIM) is programmed by the
external resistor RIL as follows.
The loop current limit programming range is from 15mA to
45mA.
Impedance Matching
The AC source impedance of the SLIC is programmed with
the external impedance network ZS as described next. To
synthesize and match Resistive line terminations the
programming network is simply a resistor (RS) as shown in
Figure 14. For complex line terminations such as the one
illustrated in Figure 1, a complex programming network is
required.
RESISTIVE IMPEDANCE SYNTHESIS
The AC source resistance of the SLIC is synthesized with a
single external resistor RS as follows:
The synthesized resistance (Z0) is determined by the
characteristic line resistance and protection resistors as
shown in Equation 5.
COMPLEX IMPEDANCE SYNTHESIS
A complex network is used in place of RS when the termination
impedance of the line is complex as shown in Figure 1.
The component RS has a different design equation than the
RS used for resistive impedance synthesis. The design
equations for each component are provided below where
RP1 and RP2 are the protection resistors and RP is a
component of the programming network.

NOTES:
2. These parameters are controlled via design and Statistical Process Control and are not directly tested. These parameters are characterized upon
initial design release and upon design changes which would affect these characteristics.
3. Input voltage = 0.636VRMS for VBH = -100V, 0.530VRMS for VBH = -85V and 0.460VRMS for -75V devices.
4. Tested per IEEE455-1985, with 368
resistors connected to the Tip and Ring terminals.
5. These parameters are tested 100% at room temperature, and are guaranteed but not tested across the full temperature range via statistical
characterization and design.
6. The power dissipation is based on actual device measurements and will be less than worst case calculations based on data sheet supply current limits.
7. Characterized with 2 x 10us and 10 x 1000us first level lightning surge waveform (GR-1089-CORE).
Electrical Specifications
Unless Otherwise Specified, TA = -40oC to 85oC, VBL = -24V, VBH = -100V, VCC = +5V, AGND = BGND = 0V,
loop current limit = 25mA. All AC Parameters are specified at 600
, 2-wire terminating impedance over the
frequency band of 300Hz to 3.4kHz. Protection resistors = 0
. These parameters apply generically to each
product offering. (Continued)
