Application Notes

1. The transformers have been developed for use as trans-

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.

2. Bandwidth specifications are typical in a 75Ωsystem.

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. TX3026T).

5. For other T3/DS3/E3/STS-1 Transformers, please see

data sheets T606, T619, T672, T663 and T668.
