AD9627
CHANNEL/CHIP SYNCHRONIZATION
The AD9627 has a SYNC input that offers the user flexible
synchronization options for synchronizing the internal blocks.
The clock divider sync feature is useful for guaranteeing synchro-
nized sample clocks across multiple ADCs. The signal monitor
block can also be synchronized using the SYNC input, allowing
properties of the input signal to be measured during a specific
time period. The input clock divider can be enabled to synchronize
on a single occurrence of the SYNC signal or on every occurrence.
The signal monitor block is synchronized on every SYNC input
signal.

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 externally synchronized to
the input clock signal, meeting the setup and hold times shown
in Table 8. The SYNC input should be driven using a single-
ended CMOS-type signal.
