For a baseband digital front-end (BDFE) processor that communicates with one or more radio-frequency integrated circuit (RFIC) chips over two or more JESD-compliant links in a multi-antenna base station, the BDFE has JESD transmitters (TXs) and receivers (RXs) that transmit and receive data to and from the RFIC chips and a time-based generator (TBGEN) that generates sync and idle signals that ensure that the processing of the different JESD TXs and RXs are aligned in time for data associated with a single logical group of antennas. The TBGEN has hardware-based alignment circuitry that generates the sync and idle signals, thereby avoiding the latency and unpredictability inherent with software-based solutions.
