AD9083 SYSREF and SYNCIN

Hi , 

Please see attached additioal details  on SYSREF for the AD9083 in an Engineering note as an interim solution while I revise the datasheet. I dont have set up and hold times for SYSREF wrt sampling clock, I expect to be able to include them in the next datasheet revision. The minimum pulse width for sysref would be same as clock period of device clock (the sampling clock). regards Brigid.

Hi Brigid san

Thank you for answer about SYSREF.

I understand SYSREF automaticall aligned device clock.

Will SYNCINB be automaticall aligned device clock,too or is synchronization unnecessary?

Best regards
