SLIC in the Active Mode
Figure 2 shows a simplified AC transmission model of the
UniSLIC14 and the connection of the TCM38C17 to the
SLIC. Circuit analysis of the UniSLIC14 yields the following
design equations:
Substitute Equation 5 into Equation 6
(
Substitute Equation 7 into Equation 8
Substitute Equation 9 into Equation 10
Substituting -V
2W
/Z
L
into Equation 11 for I
M
and rearranging
to solve for V
2W
results in Equation 12.
Z
L
where:
V
RX
= The input voltage at the V
RX
pin.
V
A
= An internal node voltage that is a function of the loop
current detector and the impedance matching networks.
I
X
= Internal current in the SLIC that is the difference between
the input receive current and the feedback current.
I
M
= The AC metallic current.
R
P
= A protection resistor (typical 30
).
Z
T
= An external resistor/network for matching the line
impedance.
V
TR
= The tip to ring voltage at the output pins of the SLIC.
V
2W
= The tip to ring voltage including the voltage across the
protection resistors.
Z
O
= The line impedance.
Z
TR
= The input impedance of the SLIC including protection
resistors.
