Abstract

Aspects of a method and system for inter integrated circuit (IC) communications utilizing a spatial multilink repeater are provided. In this regard, one or more circuits in an integrated circuit may be enabled to receive a signal and repeat the received signal to a plurality of target integrated circuits. The repeated signals may be generated by frequency shifting the received signal and a different frequency shift may be utilized for each of the repeated signals. In this regard, each of the repeated signals may be generated by quadrature down-converting the received signal by mixing it with a first local oscillator pair, up-converting the down-converted signal by mixing it with a second local oscillator pair, and adding or subtracting an in-phase portion of the up-converted signal with a quadrature-phase portion of the up-converted signal.
