Application
Pulse Specialty Components has designed Fibre Channel
dual transformers 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 contributor to jitter. The dual
package allows connection of both transmit and receive
channels, as shown in the application circuit below.
Surface-mount packagin also allows a cost-effective
solution.
1. The transformer, 51
Ω resistors, and the impedance of
the driver are matched to achieve the best return loss
(S11) for the transmitter of the 150
Ω system.
2. The total impedance of termination resistor network is
150
Ω.
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 component
and earth/chassis ground should be “AC-coupled” to
signal (digital) ground through a 0.27uF, 500v
capacitor.
