AB  - This paper studies the synchronization between the analog and digital local 
      oscillators (LOs) in bandwidth-interleaved (BI) data acquisition systems (DAQS). 
      It gives a detailed analysis of the random synchronization phase difference 
      between the analog and digital LOs in the BI-DAQS among different acquisition 
      frames. Exploiting the synchrony relation between the analog LO and sampling 
      clock of the BI-DAQS, the synchronization between analog and digital LOs, where 
      the digital LO is generated in the sampling clock domain, in each acquisition 
      frame is realized in the Field Programmable Gate Array (FPGA). A BI-DAQS platform 
      with a 5.5 GHz bandwidth and 20 Gs/s sampling rate is built to validate the 
      proposed synchronization mechanism. Experimental results in the platform show the 
      efficacy of the proposed synchronization mechanism, which consumes only a small 
      amount of the flip-flops and look-up tables in the FPGA without any additional 
      hardware assistance.
