T1/Cept/ISDN-PRI Transformers
Application Notes
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. All other paratmeters
are specified at +25C 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
requiremens 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 Moe Rejection Ratio - The CMRR for all
transformers is better than 50 dB at 1 MHz. A typical
test circuit is shown below.
6. Crosstalk Attentuation - In the dual packages, which
contain transmit and receive transformers side by side,
sucient 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 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
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:
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, such as PE-68646NL (pg. 3) is certified by
the following organizations:
Code Certificate Information
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
waveform, return loss, and balance.
12. Common Mode Chokes - The “high-frequency” 4-lines
common mode chokes shown in this data sheet
provide an eective 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.

Notes From Tables (pages 1-6):
A. Tolerance leakage inductance:
.30 μH min to .55 μH MAX.
B. OCL (primary inductance) and L
(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 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
F. Standard packaging for surface
mount “AN” and “LA” packages
is ant-static tubes. Optional Tape
& Reel packaging can be ordered
by adding “T” sux to the part
number (i.e. PE-68864NLT).
G. Safety Agency approvals
pending.
H. 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 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.
