Abstract: Die-to-die communication links for receiver integrated circuit dies within multi-die systems and related methods are disclosed for radio frequency (RF) receivers. The disclosed embodiments provide die-to-die communication links that allow for direct communication of operating parameters between receiver integrated circuit dies and other integrated circuit dies within a multi-die system so that the operation of receive path circuitry can be adjusted without requiring intervention from an external host processor integrated circuit. A variety of operating parameter information can be communicated through the die-to-die communication links so that the integrated circuit dies can quickly adjust to changing signal conditions without requiring intervention by the external host processor integrated circuit.
