ABSTRACT:
An RFIC includes first and second RF sections, first and second PHY processing modules, first and second upper layer processing modules, and memory. When the RFIC is in a first receive mode, the first RF section, the first PHY processing module, and the first upper layers processing module convert a first inbound RF signal into a first inbound audio signal in accordance with a first wireless communication protocol. When the RFIC is in a second receive mode, the second RF section, the second PHY processing module, and the second upper layers processing module convert a second inbound RF signal into a second inbound audio signal in accordance with a second wireless communication protocol. The memory stores the first and second inbound audio signals. The first PHY processing module retrieves, based on the receive mode, the first or second inbound audio signal from the memory and converts the first or second inbound audio signal into a first or second inbound analog audio signal.
