We use 2 pcs of AD7767 at daisy chain . (Formatx 01 settings)
START , SYNC_IN and SYNC_OUT pin at datasheet rev.A P24 describes below.
”In a daisy-chained system of AD7768 devices, two successive synchronization pulses must be applied to guarantee that all ADCs are synchronized."
What does "two succeessivesynchronizatoin" mean ?
(does this mean that we should input twice START for safe because START is asynchronous ?
Please let me know your advice.
