THE TALEMA GROUP • Magnetic Components for ISDN / xDSL / LAN Data Communications
Magnetic Components for E1/T1/CEPT/ISDN-PRI - T3/E3/D3/STS-1
TALEMA PROFILE
Founded in 1975, The TALEMA International Group has established itself
as a world leader in the manufacture of toroidal transformers and related
magnetic components. Our strong technical engineering expertise has
contributed to the growth of our current workforce to over 1,000 employees
in manufacturing locations in Ireland, the Czech Republic and India.
QUALITY
The TALEMA Group has a total commitment to quality. All facilities
maintain very stringent Quality Control and Quality Assurance
procedurees and are certified to and manufacture in accordance with
ISO-9001 and meet a broad range of International Standards including
UL, VDE, IEC, and EN.
Over the years The Talema Group has succeeded in designing, producing
and delivering in excess of 35 million transformers to its customers. The
recent incorporation of xDSL technology into our extensive range of
Telecom and LAN magnetics offerings, such as ISDN, 10Base-T, Ethernet
transformers for 100/1000Base-T, has broadened our market offering to
an even higher level.
Performance has been proven in the many design in’s of our products.
The fact that we maintain a ship-to-stock vendor rating with over 200
national and international companies is, to us, the best testimonial of
our commitment to quality.

IC - E1 / T1 / PRI / CEPT Transformer Selection Guide
Talema manufactures a wide range of transformers for all 1.544 and 2.048Mbbs applications. A full listing of LIU Transceiver IC’s with
recommended Talema transformers is listed on the following cross reference chart.
Performance has been proven in the many design-ins of our products in these applications. Quality and consistency is guaranteed through 100%
testing of the specified parameters for Primary Inductance, Leakage Inductance, Turns Ratio, DC resistance and Interwinding Capacitance. This
ensures that the Return Loss and Pulse Waveshape requirements of ITU-T G.703 and ANSI T1.102 can be met. Additionally all parts are 100%
tested for 1500V minimum isolation.
Temperature Performance
Products are offered for both standard temperature (Commercial 0° to 70°C) and extended temperature (Industrial -40° to 85°C) applications.
Required minimum inductance levels are maintained at the lower temperature limits. Advanced design means that the MJM series may be used for
either temperature classification.

Notes:
1. Dallas IC’s use either a 1:1.15 or a 1:1.36 ratio transformer depending on the application. Consult the Dallas application notes or contact Talema.
2. Consult Siemens Application Note 12.90 (‘Just a Single Line Transformer Type for all IPAT (PEB2235) Applications’) for calculation of resistor values.
3. The Dual Transformer types MDM-010 and MDM-021 are electrically identical but have different schematics. Either part may be used with the PEB2254 and PEB2255.
4. See Level One Application Note 118 (‘Transformer Specifications for Level One Transceiver Applications’) for further details on the choice of transformer ratios.
