Abstract
A tuner circuit includes circuitry to produce a first DSP frame based on a first RF signal and includes an inter-chip receiver circuit coupled to an inter-chip link and configured to receive an inter-chip frame. The inter-chip receiver circuit is configured to detect a start of frame symbol of the inter-chip frame and to extract a DSP offset and data related to a second DSP frame from the inter-chip frame. The tuner circuit further includes a digital signal processor coupled to the circuitry and to the inter-chip receiver circuit. The digital signal processor synchronizes the first DSP frame with the second DSP frame based on the start of frame symbol and the digital signal processor offset. The digital signal processor performs a selected antenna diversity operation on the first and second DSP frames to produce an output signal.
