A. A center-tapped winding can be created by connecting two ends of a split center winding together on the printed circuit board. In ISDN-S applications, the primary
winding is the line side transformer winding.
B. Minimum primary inductance and maximum distributed capacitance satisfy the transmitter output and receiver input impedance requirements of CCITT I.430 for both
the TE and the NT. The maximum distributed capacitance allows sufficient margin for the capacitance of the IC and a protection diode network. It is consistent with
the overall maximum value specified and the permitted length of the basic access TE cord.
C. The maximum specified unbalanced DC current capability is based on ±0 mH minimum primary OCL.

Application Notes
1. General Information – The S-interface is the standard-
ized four-wire digital telephone access point defined by
the CCITT I-series recommendations for the Integrated
Services Digital Network. This “basic rate access” accom-
modates two 64 Kbps “B-channels” for information, one
16Kbps “D-channel” intended for signaling and control, and
48Kbps for framing and other purposes, giving a total rate
of 19±Kbps. The CCITT physical layer recommends that the
user network interface be transformer coupled.
The use of a transformer-chip pair assures that all require-
ments of CCITT I.430 are met with respect to pulse wave-
form templates, impedance and longitudinal balance. In
addition, the transformers provide the isolation voltages
required by the regulatory agencies and are capable of
passing surge voltage tests.
2. Safety Standards Recognition – All transformers listed
in this data sheet are recognized to UL 14ꢀ9 and UL 19ꢀ0 as
a basic insulation barrier.
The transformeAr provides isolation for the line card or the
terminal from the line. It is also a way to provide phantom
power feeding to the terminal over the S-loop. Each end
requires a transmit and a receive transformer. Chokes are
used in some applications to reduce common mode noise.
3. Flammability – Materials used in the products are recog-
nized UL94-VO. Products meet the requirements of IEC
69ꢀ-±-± (needle flame test).
4. For more application notes please refer to data sheet T604.
Transformers described in this data sheet are matched to
the transceivers offered by the IC manufacturers listed.
Common Mode Chokes
Refer to data sheet G00± for selection of low and high frequency common mode chokes.
