A integrated circuit (IC) chip can include a root timer that generates a frame pulse based on a start trigger signal. The IC chip can also include a hardware clock control that provides a clock signal based on a selected one of the frame pulse and the synchronization signal provided from one of the root timer and another IC chip. The IC chip can further include a plurality of analog to digital converters (ADCs). Each of the plurality of ADCs being configured to sample an output of a respective one of a plurality of radio frequency (RF) receivers based on the clock signal.
