The transformers have been developed for use as transmit and receive transformers in T or DS links, using bit rates of.7 Mbps and BZS coding on coaxial cable. The characteristics allow compliance with the pulse templates of CCITT G.70 as well as ATT T.A.. The transformers are also suitable for the E interface at.8 Mbps with HDB coding or STS- applications, at.8 Mbps according to Bellcore TA-NWT-000. The LC- and QC- packages are pin-compatible with T- and T- -pin DIP packages.. Bandwidth specifications are typical in a 7 Ω system. Return loss meets the requirements of G.70. Materials used in the products are UL9-V0 recognized. Products meet the requirements of IEC 9-- (Needle Flame Test).. The surface mount LS-package is available with optional Tape & Reel packaging. To order, add a T suffix to the part number (e.g. PE-97NLT).. The Transwitch MRT TXC-000 chip is also designed to operate in. and 8.8 Mbps interfaces. A : transformer (PE-9) is recoended.
