Abstract
A low-cost, high-speed, bus-based communication system is provided that includes a master electronics card, a number of slave electronics cards, and a backplane that interconnects the master and the slave electronics cards via a serial bus, a parallel bus and some common signals for clocking and synchronization.
Claims20
A communications system comprising a master electronics card, the master electronics card including:
- a first driver that outputs a first clock signal, the first clock signal having a first clock period;
- a second driver that outputs a framing signal, the framing signal having a plurality of framing periods, and
- a third driver that outputs a first data signal such that a plurality of first bytes of data is output by the third driver during each framing period, each first byte of data having bits of data that are output during different first clock periods.
A method of operating a communications system comprising the steps of:
- outputting a first clock signal, the first clock signal having a first clock period;
- outputting a framing signal, the framing signal having a plurality of framing periods, and
- outputting a first data signal such that a plurality of first bytes of data is output during each framing period, each first byte of data having bits of data that are output during different first clock periods.
