Can two AD7606C-18 be used over SPI for 16-Channel simutaneous sampling?

Hello Everyone,

I have seen a document (CN-0148) that shows using two AD7606 (should be the same for AD7606C-18) can be used with parallel data output (all 16 bits) and the parallel pins of both the ADCs are connected together and then synchronized by separate CS pins. 

My question is can a similar type of synchronization be done by using just SPI instead of parallel interface? 

Thank you.
