Application Notes
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 packaging also allows a cost-effective solution.

Fig. 1 - Typical Application Circuit
1. The transformer, 51Ω resistors, and the impedance of the driver are matched to achieve the best return
loss (S11) for the transmitter of the 150Ω 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 .027uF, 500V
capacitor.
