About multi channel synchronization with AD7616


i'm trying to use ad7616 for new design which is having more than 80 channels on 2FMC's and i need to design for synchronized data... can anyone tell me how to use this IC for synchronization purpose without any clk or sync pin's.

and how to conform that data is processing at what speed without ref clk in parallel communication.

how much timing relaxations can be taken in ad7616-p than ad7616

its little bit urgent ...any one can u plz help me to get knowledge about this to finish this design...

thank you in advance

  • Hi,

    Apologies. Missed the thread.

    You may use the CONVSTx pins to synchronize conversion. These pins can be tied together to simultaneously initiate conversion of the AD7616. When in parallel mode to monitor the data processing you may want to check the BUSY pin. The BUSY pin remains high when AD7616 is still in conversion and goes low when conversion is complete. Checking this pin would give you idea the conversion time of the AD7616.
