ABSTRACT:
A high speed bus structure is described which employs an ordinary flat ribbon cable. ECL receivers are coupled to conductor pairs of the cable through resistors which change the capacitive load of the ECL receivers to a resistive load. The receivers are coupled to the cable through a plurality of connectors having spaced-apart pins. The pins in each connector engage less than all of the conductor pairs, thus a plurality of connectors are required to completely couple receivers to all the conductors in the cable. This connector arrangement substantially reduces the parasitic capacitance loading on the cable. The invented high speed bus is able to effectively function at 100 MHz with 80 feet of cable and with 16 receivers coupled to each conductor pair.
