T3/DS3/E3/STS-1 TRANSFORMERS
Dual SMT, Extended Temperature Range
Application Notes
mit 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
34.368Mbps with HDB3 coding or STS-1 applications, at
51.84Mbps according to Bellcore TA-NWT-000253.
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).
