Abstract :
A method to drive a FASTBUS cable segment over long distance is described. The signal level transmitted is converted from standard FASTBUS cable segment signal to a TTL differential output; the scheme increases noise immunity. In addition, the receiver has a wide tolerance of common mode range of +/-15 V. By applying a deskewing mechanism in the extender module, we have achieved more than 1010 transactions of FASTBUS without any error with a cable length of 100 m.
