DTM-100 Datasheet, PDF (1/1 Pages) Nuvotem Talema – T3/DS3/E3/STS-1 Tri-Port Transformer Modules

DTM Series • T3/DS3/E3/STS-1 Tri-Port Transformer Modules
These 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
• manufactured in an ISO-9001:2000, TS-16949:2002
and ISO-14001:2004 certified Talema facility
• fully RoHS compliant and meets lead free reflow
level J-STD-020C
