To allow low cost interconnection and thus reduce the EMI. The wide bandwidth of these devices minimizes between supercomputers and high-end peripherals, the ANSI X3T9.5 FC-0 data dependent jitter by providing fast signal rise times. In addition, Committee has specified coaxial interconnects as an alternative to optical use of the proper transformers will provide sufficient low-end bandwidth fibre cable. Although the transmission distance through alternative cable to minimize baseline wander, another contributor to jitter. Low-end bandwidth is a function of the channel impedance and the primary is limited in distance, it offers a significant cost advantage over the optical inductance of the transformer. The selection table, on the front side of fibre interface. Pulse has designed the fibre channel dual transformers this data sheet, matches the proper transformer to the different cables specifically for point-to-point coupling to coaxial cable. This transformer and wdata rates. Each of the coaxial cables has a 75  characteristic series complies with the ANSI X3T9.5 FC-0 specification over 133, impedance. 266,and 531Mbps data rates over distances of up to 100 meters on coaxial cable. The dual package allows connection of both the transmit and receive channels, as shown in the application circuit below. Surface mount The isolation transformers protect the station from static charges that packaging allows a cost effective solution while providing over -40dB may develop on the cable and prevent ground loop currents from of crosstalk attenuation out to 800 MHz. The transformers are available in being transferred between stations. When coaxial links are used, the either tubes or Tape & Reel packaging. transformers also provide a balance to single-ended connections between the transmitter/receiver IC and the coax.
