AD9627
CHANNEL/CHIP SYNCHRONIZATION
The AD9627 has a SYNC input that allows the user flexible
synchronization options for syncing the internal blocks. The
sync feature is useful to guarantee synchronized operation
across multiple ADCs. The input clock divider and the signal
monitor block can be synchronized using the SYNC input. The
input clock divider can be enabled to sync on a single
occurrence of the sync signal or on every occurrence. The
signal monitor syncs on every SYNC input.
The SYNC input is internally synchronized to the sample clock,
however to ensure there is no timing uncertainty between
multiple parts the SYNC input signal should be synchronized to
the input clock signal. The SYNC input should be driven using
a single ended CMOS type signal.
