hi everyone....

a warmly  wish of new year 2014....

I am using two AD9959 Ics in master- slave configuration , to synchronise them i hav select AUTOMATIC MODE SYNCHRONISATION by setting FR2[7] = 1. To control these Ics through a FPGA , if I choose 4-bit SERIAL mode then SYNC_I/O feature will not be available to me ( as per AD9959 datasheet). so, can I proceed with the same or I hav to switch for 2-bit serial mode and  if switch how tit will affect the functioning of the Ics. Also comment on the utilisation of SYNC_I/O signal in this regard.
