Abstract :
RF-interconnect (RFI) can greatly improve the signal-to-noise ratio (SNR) in a high-speed digital interface system by separating the data and the noise in the frequency domain and suppressing the switching noise by the highpass channel characteristics. Experimental characterisation results are presented of a prototype multi-I/O RFI channel. The potential SNR improvement is estimated to be 10 dB compared to conventional digital interface systems. The improved system SNR can lead to enhanced data rate with reduced signalling level in RFI.
