On page 107 of the specification for the DAC37J82(May 2014) is a procedure for initializing. In general it states that once the DAC is set up, a SYSREF must be generated. In response, the DAC sets Sync_n low to begin the CGS alignment.
1) Based on this procedure, it appears that the synchronization process must be initiated by applying SYSREF to the DAC: the DAC cannot initiate the synchronization (ie assert sync_n) autonomously. Is this the case, or is there a way that once the DAC is set up it automatically asserts sync_n?
2) What is the process for re-synchronization in the case when the DAC initiates the re-sync? Does the DAC automatically reset itself and generate Sync_n = 0, or is some external intervention required before the DAC can assert Sync_n?
