Abstract

The SpaceFibre provides numerous advantages over the SpaceWire: QoS, FDIR, high transmission rate, galvanic isolation, lower cable mass. At moderate speeds, e.g. 10-200 Mbps, the SpaceFibre interface implementation can be significantly simplified with oversampling techniques, which does not require PLLs and analog CDR blocks. It makes possible fully digital implementation of the SpaceFibre interface in a simple ASIC or FPGA. This paper presents an oversampling technique based on digital signal processing. The technique allows to enhance transmission rate, operational distance, phase/amplitude distortion tolerance and higher noise immunity in compare with the traditional edge detection method.
