DJM Oct-07 - Nuvotem Talema

DJM Series • T3/DS3/E3/STS-1 Dual Interface Transformers
These miniature modules contain both transmit and receive
transformers designed for use in in T3/DS3 applications using
bit rates off 44.736Mbps, E3 interfaces at 34.368Mbps and
STS-1 applications at 51.84 Mbps The transformers are typical
for 75 ohm bandwidth applications requiring a very fast rise
times.
Features
• low cost SMD for pick and place compatability while providing
consistent and reliable coplanarity
• low leakage inductance
