I am Synchronizing 4 DDS of AD9910, and i would like to know some details.
i read that the I/O Update needs to be synchronized with the Sync Clock.
Is it necessary to take all the 4 Sync Clocks and use Flip Flop to latch them with there I/O UPDATE
or it is enough to Latch it with the Master Sync Clk ?. is it necessary to latch at all ?.
today i use one dds and don't latch it and it works good.
and another Question concerning SPI:
i am using arduino to transfer the data and i want to take the spi output of the arduino to all the 4 DDS
you think that one output can handle the 4 dds inputs ? is it necessary to add buffers?
