NOTES FROM TABLES (pages 1 - 6):
A. Toleranced leakage inductance: .30 µH min to .55 µH MAX.
B. OCL (primary inductance) and LL (leakage inductance) are
measured at the primary winding. Turns ratio is specified
primary: secondary. (CT = Center Tap; CS = Split Center
Tap).
C. To make a 1CT:1 ratio from a 1CT:2CT ratio, use only one
half of the secondary (2CT) winding.
D. For Reinforced 3 kVrms Dual SMT Transformers, refer to
data sheet T617. For Quad SMT Transformers, refer to
data sheet T615. For Octal SMT Transformers, refer to
data sheet T622.
E. Dual Ratio Transformers: 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 the desired turns ratio:
F. Standard packaging for surface mount “AN” and “LA”
packages is anti-static tubes. Optional Tape & Reel
packaging can be ordered by adding “T” suffix to the part
number, (i.e. PE-65866NLT).
G. PE-68618NL and PE-64950NL: The fault locate winding is
(7-8).
H. Safety Agency approvals pending.
I. The turns ratio of these devices have been designed, in
conjunction with semiconductor vendor recommendations,
to allow connections to various terminations (e.g. 75 Ω or
120 Ω with the same transformer). For example T1075NL
can be used with the Siemens PEB 2235 to achieve
connection to the 75 Ω or 120 Ω cable. For 75 Ω termination,
the PEB 2235 requires the following turns ratio: 1:1.57 (TX)
and 1:1.26 (RX) which can be achieved using pins (1-2):(15-
16) for TX and (10-11):(5-8) for RX. For 120 Ω, the following
turns ratio are required: 1:2 (TX) and 1:1 (RX), which are pins
(1-2):(16-14) for TX and (9-11):(5-8) for RX on the T1075NL.
1. 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 for all low temperature models with the
exception of PE-68827NL which is 800 µH minimum and PE-65836NL which is
300 µH minimum. All other parameters are specified at +25°C only. Standard
temperature range is 0°C to +70°C.
2. ET Product — All coils have an ET product of 10 V-µsec minimum.
3. Flammability — Materials used in the products are recognized as UL94-VO
approved. Products meet the requirements of IEC 695-2-2 (Needle Flame Test).
4. Balance Characteristics — The transformers meet the requirements for
longitudinal balance of FCC part 68.
5. Common Mode Rejection Ratio — The CMRR for all transformers is better
than 50 dB at 1 MHz. A typical test circuit is shown below.
6. Crosstalk Attenuation — In the dual 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 50 dB or better from 100 kHz
to 10 MHz. This result was established with the test circuit shown below.
7. 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.
Frequency 50-100 kHz 100 kHz-2 MHz 2-3 MHz
Return Loss
TX 9 dB 15 dB 11 dB
RX 12 dB 18 dB 14 dB
8. Surge Voltage Capability – All transformers and chokes meet surge voltage
tests according to the most stringent regulatory documents when system
designs include the proper voltage and current suppression devices:
Metallic Voltage: 800 V peak, 10/560 µsec
Longitudinal Voltage: 2,400 V peak, 10/700 µsec
9. Isolation Voltage — 100% of transformers are tested during production to
the specified isolation voltage level.
10. Safety Agency Recognition — Parts listed as “Recognized” or “Certified”
meet Underwriter Laboratories, UL 1459 and UL 1950 per file E133523 (S).
Transformers with Reinforced Insulation according to IEC950 series
PE-68630NL—PE-68788NL (pg. 3) are certified by the following organizations:
Code Certificate Information
T TÜV, EN 60 950/EN 41003, Cert. R9371358, reinforced insulation.
U UL 1459/UL1950, File E133523 (S), reinforced insulation.
11. 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 wave-
form, return loss, and balance.
12. Common Mode Chokes — The “high-frequency” 4-lines common mode
chokes shown in this data sheet provide an effective means of compliance
with national and international regulations on EMI. They are designed to be
used in conjunction with Pulse’s T1/CEPT transformers as shown in the typical
application below. Crosstalk is typically -70 dB at 1 MHz and -55 dB at 10 MHz.
