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 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 TANWT-000253. 2. Bandwidth specifications are typical in a 75 W 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. For those applications requiring a 1:1 turns ratio on the transmit side, use only one half of the secondary (2CT) winding. 4. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. TS3026T) For More Information : UNITED STATES (Worldwide) UNITED KINGDOM (Northern Europe) FRANCE SINGAPORE (Southern Europe) (Southern Asia) TAIWAN, R.O.C.
