摘要：
A multiple input multiple output (MIMO) RF transceiver system includes a plurality of RF transceiver ICs, a crystal, and master oscillation coupling. Each of the plurality of RF transceiver ICs includes crystal oscillator circuitry. Crystal oscillator circuitry of the first RF transceiver IC and a crystal are operable to produce a master oscillation. Master oscillation coupling couples the master oscillation produced by the first RF transceiver IC to the at least one other RF transceiver IC. In one embodiment, the master oscillation is passed from the first RF transceiver IC to each other transceiver RF ICs. In another embodiment, the master oscillation is used to produce a slave oscillation at a second RF transceiver IC and subsequent RF transceiver ICs produce there own slave oscillation based upon a slave oscillation received from a prior RF transceiver IC.
