T3/DS3/E3/STS-1 TRANSFORMERS
Designed for T3, DS3, E3 and
STS-1 Interfaces
Application Notes
1. The transformers have been developed for use as transmit
and receive transformers in T3 or DS3 links, using bit rates of
44.736 Mbps and B3ZS coding on coaxial cable. The charac-
teristics allow compliance with the pulse templates of CCITT
G.703 as well as ATT T.A.34. The transformers are also suit-
able for the E3 interface at 34.368 Mbps with HDB3 coding or
STS-1 applications, at 51.84 Mbps according to Bellcore TA-
NWT-000253. The LC-1 and QC-1 packages are pin compati-
ble with T1-1 and T4-1 6-pin DIP packages.
2. Bandwidth specifications are typical in a 75 Ωsystem. Return
loss meets the requirements of G.703. Materials used in the
products are UL94-V0 recognized. Products meet the require-
ments of IEC 695-2-2 (Needle Flame Test).
3. The surface mount LS-1 and TR-2 packages are available with
optional tape and reel packaging. To order, add a “T” suffix to
the part number (i.e.: PE-65967T).
4. The Transwitch MRT TXC-02050 chip is also designed to
operate in 6.312 and 8.448 Mbps interfaces. A 1:1 transformer
(PE-64934) is recommended.
5. All transformers listed on this data sheet are RoHS-5
compliant. For RoHS-6 compliant versions of these parts,
please contact Pulse.
