Abstract: A baseband IC for performing digital communication with an RFIC and a device including the same. The baseband IC for performing digital communication with an RFIC includes a digital interface circuit configured to receive a frame signal including at least one sampled signal from the RFIC according to a digital interface protocol, reconstruct the at least one sampled signal from the frame signal, and transfer the reconstructed sampled signal to a baseband modem in synchronization with a reception reference signal, and a sample synchronization manager configured to generate the reception reference signal, wherein the frame signal is transmitted from the RFIC to the baseband IC in synchronization with a transmission reference signal.
