Baseband integrated circuit for performing digital communication with radio frequency integrated circuit and device including the same

A wireless communication device, comprising:

• a radio frequency integrated circuit (RFIC);
• and
• a baseband IC to perform digital communication with the RFIC,
• wherein the baseband IC includes:
• a digital interface 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 to generate the reception reference signal, wherein the frame signal is to be transmitted from the RFIC to the baseband IC in synchronization with a transmission reference signal.

A baseband integrated circuit (IC) for performing digital communication with a radio frequency integrated circuit (RFIC), comprising:

• first logic to reconstruct at least one sampled signal from a frame signal and to output the reconstructed at least one sampled signal to a baseband modem in synchronization with a reception reference signal;
• and
• second logic to generate the reception reference signal,
• wherein the first logic is to receive the frame signal from the RFIC in synchronization with a transmission reference signal.
