Application Notes
Mechanical Schematic
T-3200SCT
Pulse Specialty Components has designed Fibre Channel dual trans-
formers specifically for point to point coupling to 150 twinax cable.
The isolation transformers protect the station from static charges that
may develop on the cable, and prevents ground loop currents from
being transferred between stations. The devices have also been
designed to provide common mode rejection within the transmission
band and thus reduce EMI. The wide bandwidth of these devices
minimizes data dependent jitter by providing fast signal rise times.
Low-end bandwidth also minimizes base-line wander, another con-
tributor to jitter. The dual package allows connection of both transmit
and receive channels, as shown in the application circuit below.
Surface-mount packaging also allows a cost-effective solution.
1. The transformer, 51W resistors, and the impedance of the driver
are matched to achieve the best return loss (S11) for the transmit-
ter of the 150W system.
2. The total impedance of termination resistor network is 150 W.
3. When laying out PCB, transmission line methods must be utilized
to maintain return loss and signal integrity. Transformer must be
located within .50” of the DB9 connector.
4. It is recommended that the center tap (CT) of transformer(s), cable
side, be connected to earth/chassis (cable shield) ground either
directly or via a transient voltage suppressor (TVS) type compo-
nent and earth/chassis ground should be “AC-coupled” to signal
(digital) ground through a .027uF, 500V capacitor.
