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 (100Ω) and CEPT (75Ω & 120Ω). For
specific connection information and resistor values, refer to IC
vendors' data book.
D.
Dual Ratio Transformer
(T1071, T1111 and T1145)
— 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:

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. T1063T).
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 10V-µsec minimum.
Flammability
— Materials used in the products are recognized
as UL94-VO approved. Products meet the requirements of
IEC 695-2-2 (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.
8.
9.
Isolation Voltage
— 100% of transformers are tested during
production to the specified isolation voltage level.
General Information
— The transformers are specifically
designed for use in 1.544Mbps (T1), 2.048Mbps (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 -65dB or better.

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 65dB or better. This result was established
with the test circuit shown below.

Return Loss
— ITU-T G.703 and European national regulatory
documents specify minimum return loss levels. The transformers
will allow these limits to be complied within the situations where
they are applicable.
