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. Dual Ratio Transformer 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. T1064NLT).

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.

T1/E1/CEPT/ISDN-PRI TRANSFORMERS

Quad Port T1/E1 with 8 Transformers, 1500 Vrms

Application

Metallic Voltage: 800 V peak, 10/560μsec

Longitudinal Voltage: 2,400 V peak, 10/700μsec

1. ET Product - All coils have an ET product of 10 V-μsec

minimum.

8. Isolation Voltage - 100% of transformers are tested during the

speciﬁed isolation voltage level.

2. Flammability - Materials used in the products are

recognized as UL94-VO approved. Products meet the

IEC 695-2-2 requirements (Needle Flame Test).

9. 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.

3. Balance Characteristics - The transformers meet the

requirements for longitudinal balance of FCC part 68.

4. Common Mode Rejection Ratio - the CMRR for all

transformers is better than 50dB at 1MHz. A typical test

circuit is shown below.

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.

Typical Application

5. Crosstalk Attentuation - In the packages which contain

transmit and receive transformers side by side, suﬃcient

crosstalk attentuation is achieved by the inherent

characteristics of the toroid cores as well as by their

proper positioning. The crosstalk attentuation is typically

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

circuit shown below.

6. 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

with the situations where they are applicable.
