CHANNEL/CHIP SYNCHRONIZATION

The AD9640 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.
