Can someone provide a detailed explanation for synchronizing multiple DAC3171 devices for a phase coherent output. Here's what's stated in the datasheet with no further explanation on how this works:
7.4.1 Synchronization Modes
There are three modes of syncing included in the DAC31x1: NORMAL Dual Sync, SYNC ONLY, and SIF_SYNC.
• NORMAL Dual Sync: The SYNC pin is used to align the input side of the FIFO (write pointers) with the A(0)
sample. The ALIGN pin is used to reset the output side of the FIFO (read pointers) to the offset value.
Multiple chip alignment can be accomplished with this kind of syncing.
