AD6643
CHANNEL/CHIP SYNCHRONIZATION
The AD6643 has a SYNC input that allows the user flexible
synchronization options for synchronizing the internal blocks.
The sync feature is useful for guaranteeing synchronized operation
across multiple ADCs. The input clock divider can be synchronized
using the SYNC input. The divider can be enabled to synchronize
on a single occurrence of the SYNC signal or on every occurrence
by setting the appropriate bits in Register 0x3A.

The SYNC input is internally synchronized to the sample clock.
However, to ensure that there is no timing uncertainty between
multiple parts, synchronize the SYNC input signal to the input
clock signal. Drive the SYNC input using a single-ended CMOS
type signal.
