Synchronizing AD6655 with AD9910 SYNC

Dear AD experts

 

This issue was asked in the "Clock and timing" section (http://ez.analog.com/message/107201#107201) but with no good answer yet.

 

I want to SYNC two AD9910 and two AD6655 (operating with the same 600 MHz clock), where the AD9910 provides the SYNC.

 

Unfortunately or not, AD9910 provides 1:16 SYNC and obviously uses 1:16 scheme as well in SYNC in,  and the AD6655 uses 1:1 sync (or a single start SYNC which I do not want). I was considering the ADCLK846 as the SYNC distributor, but it seems that I need to multiply the SYNC signal first. Am I? Any other smarter alternative?

 

Thanks, Alon.
