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. The LC-1 and QC-1 packages are pin compatible with T1-1 and T4-1 6-pin DIP packages. 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-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. 2. Bandwidth specifications are typical in a 75 Ω system. Return loss meets the requirements of G.703. Materials used in the 5. All transformers listed on this data sheet are RoHS-5 compliant.
