Abstract
Systems and methods for simultaneous sampling of serial digital data streams from multiple analog-to-digital converters (ADCs), including in distributed antenna systems, are disclosed. In one embodiment, a controller unit samples a plurality of serial digital data streams simultaneously. To allow the controller unit to sample the multiple serial digital data streams simultaneously from a plurality of ADCs, the controller unit is configured to provide a plurality of data input ports. Each of the ADCs is coupled to a common chip select port and clock signal port on the controller unit. The controller unit communicates a chip select signal on the chip select port to activate all of the ADCs simultaneously to cause each of the ADCs to provide its respective digital data stream to the respective data input port of the controller unit simultaneously for sampling. As a result, fewer or lower-cost components may be used to sample multiple ADCs.
