T1/E1/CEPT/ISDN-PRI TRANSFORMERS
Quad Port T1/E1 with 8 Transformers, 1500 Vrms
Notes from Electrical Specifications Table
A. OCL
(primary inductance) is measured at the primary winding. Turns ratio is
specified primary: secondary. (CT = Center Tap).
B. To make a 1CT:1
ratio from a 1CT:2CT ratio, use only one-half of the secondary
(2CT) winding.
C. It is possible
to use the same transformer model for the three impedance levels
of T1 (100 W) and CEPT (75
Ω
& 120
Ω).
For specific connection information and
resistor values, refer to IC vendor’s data book.
D. Dual Ratio Transformer
(T1071NL and T1145NL) — These transformers have
tapped secondary windings to provide two turns ratios (T/R). Use the entire
primary winding and connect the secondary pins listed below to obtain desired
turns ratio:

E. Standard packaging
for the surface mount package is anti-static tubes. Optional
Tape & Reel packaging can be ordered by adding a “T” suffix to the part
number, (i.e. T1063NLT).
F. Extended Temperature
Range Models — For extended temperature range
transformers (-40°C to +85°C operating temperature range), OCL (Open Circuit
Inductance) for the primary winding) is specified at both -40°C and +25°C. At
-40°C, OCL is 600 µH minimum. All other parameters are specified at +25°C
only. Standard temperature range is 0°C to +70°C

ET Product
— All coils have an ET product of 10 V-µsec minimum.
Flammability
— Materials used in the products are recognized as UL94-VO
approved. Products meet the IEC 695-2-2 requirements (Needle Flame Test).
Balance Characteristics
— The transformers meet the requirements for
longitudinal balance of FCC part 68.
Common Mode Rejection Ratio
— the CMRR for all transformers is better
than 50dB at 1MHz. A typical test circuit is shown below.
9.
the specified isolation voltage level.
General Information
— The transformers are specifically designed for use
in 1.544 Mbps (T1), 2.048 Mbps (CEPT) and ISDN Primary rate (PRI) interface
applications. They are matched to the majority of the line interface transceiver
ICs currently available. Use of the proper transformer allows the interface
circuit to comply with ITU-T G.703 and other standards regarding pulse
waveform, return loss, and balance.

10. Common Mode Chokes
— Additional high-frequency 4-line common mode
chokes may be used to provide an effective means of complying with national
and international regulations on EMI. The common mode chokes are designed
to be used in conjunction with Pulse’s T1/CEPT transformers as shown in the
typical application below. Crosstalk is typically -65 dB or better.

5.
Crosstalk Attenuation
— In the packages which contain transmit and
receive transformers side by side, sufficient crosstalk attenuation is achieved
by the inherent characteristics of the toroid cores as well as by their proper
positioning. The crosstalk attenuation is typically 65 dB or better. This result
was established with the test circuit shown below.
