Application Notes
1. The transformers have been developed for use as transmit
and receive transformers in T3 or DS3 links, using bit rates
of 44.736Mbps and B3ZS coding on coaxial cable. The
characteristics allow compliance with the pulse templates of
CCITT G.703 as well as ATT T.A.34. The transformers are
also suitable 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 compatible with T1-1 and T4-1 6-pin DIP packages.
2. Bandwidth specifications are typical in a 75Ω system.
Return loss meets the requirements of G.703. Materials used
in the products are UL94-V0 recognized. Products meet the
requirements 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-65967NLT).
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.
