SONET/SDH
Dual Line Interface Transformer for
E4/STM-1 Applications
Application Notes:
Pulse has designed the ST6200T, SONET/SDH dual line interface
transformer specifically for high-speed, STM-1/E4 serial data
interfaces utilizing 75
W
coax cable. The isolation transformer
protects the station from static charges that may develop on the
cable and prevents ground loop currents from being transferred
between stations. These devices have also been designed to
provide inherent common rejection within the transmission pass
band and thus reduce EMI. The high bandwidth of these devices
minimizes data dependent jitter (DDJ) by providing fast signal rise
times with minimal signal distortion. Insertion loss is typically less
than
–
3 dB within 10 MHz to 320 MHz passband and return loss is
typically greater than
–
15 dB (8 MHz to 240 MHz) with 75
W
load
(this can be effected by circuit board layout and other external
electrical parasitics). With traditional coaxial links, the transformer
also provides a balanced differential to single-ended connection
between the transmitter/receiver IC and the coax. The dual package
allows connections of both transmit and receive channels as shown
in the Application Circuit below. The auto-insertable SMD packaging
allows for a cost-effective solution for the application.
