sync multi AD9643

 I am using two dual channel adc ad9643. I want know how to use SYNC pin of those ADC to synchronize  ADC data output . Sampling clk for all adc is same and generated from a single crystal oscillator( same source). 

 Sampling clk is 200MHz , clock divider is not used。 As the datasheet show, sync is used to sync clock divider. So, if I do not used clock divider,  Does it mean that each ADC is inherently synchronized and does not require a sync signal?

Another question, If my AD9643 is on different PCB board, clock is also  same source,  did sync signal necessary to keep sync?
