Transformer Parameters
Transformer ratio;
Device side : Line side
Main inductance of windings on the line side
Leakage inductance of windings on the line side L
Coupling capacitance between the windings on
the device side and the windings on the line side
DC resistance of the windings on device side
DC resistance of the windings on line side
Transmitter
The transmitter requires external resistors R
voltage to the pulse mask (nominal 750 mV according to ITU I.430, to be tested with the
test mode “TM1”) on the one hand and in order to meet the output impedance of
minimum 20
on the other hand.
Note: The resistance of the S-transformer must be taken into account when

dimensioning the external resistors R
components (e.g. a choke), then the resistance of these additional components
must be taken into account, too.
