FIBRE CHANNEL
DUAL TRANSFORMERS
For Use with 75Ω Coaxial Cable
Application Notes:
Fibre channel is a bi-directional point-to-point serial data link, structured
for high performance transmission. To allow low cost interconnection
between supercomputers and high-end peripherals, the ANSI X3T9.5 FC-0
Committee has specified coaxial interconnects as an alternative to optical
fibre cable. Although the transmission distance through alternative cable
is limited in distance, it offers a significant cost advantage over the optical
fibre interface. Pulse has designed the fibre channel dual transformers
specifically for point-to-point coupling to coaxial cable. This transformer
series complies with the ANSI X3T9.5 FC-0 specification over 133,
266,and 531Mbps data rates over distances of up to 100 meters on coaxial
cable.
The isolation transformers protect the station from static charges that
may develop on the cable and prevent ground loop currents from
being transferred between stations. When coaxial links are used, the
transformers also provide a balance to single-ended connections between
the transmitter/receiver IC and the coax. The devices have also been

designed to provide common mode rejection within the transmission band
and thus reduce the EMI. The wide bandwidth of these devices minimizes
data dependent jitter by providing fast signal rise times. In addition,
use of the proper transformers will provide sufficient low-end bandwidth
to minimize baseline wander, another contributor to jitter. Low-end
bandwidth is a function of the channel impedance and the primary
inductance of the transformer. The selection table, on the front side of
this data sheet, matches the proper transformer to the different cables
and wdata rates. Each of the coaxial cables has a 75  characteristic
impedance.
The dual package allows connection of both the transmit and receive
channels, as shown in the application circuit below. Surface mount
packaging allows a cost effective solution while providing over -40dB
of crosstalk attenuation out to 800 MHz. The transformers are available in
either tubes or Tape & Reel packaging.
