      Hi daidaishannon,
      

      Yes, AD9213's SYNCINB signal, and JESD204B SYNC signals in general, should be DC-coupled. This is not so much a device requirement but rather it is a system requirement. The JESD204B SYNC signals are asserted when needed and otherwise will be idle. Long idle periods can be an issue when AC coupled.
      

      Thank you.
      

      Doug
