AD9081 Single NCO

Category: Hardware
Product Number: AD9081-4D4AC
Software Version: N/A

Hi,

Is it possible to use a single NCO for all four DAC or all four ADC channels, thus ensuring all four channels' NCOs are synchronised, or is the only solution to supply all four NCOs with the SYSREF and then run a synchronisation (i.e., phase alignment) scheme?

From the datasheet I'm assuming the latter is the case, but just want to confirm.

Kind regards,

Deng

Hello,

You are correct in that the SYSREF and NCO phase-alignment method outlined in UG1578 is the only solution for synchronization.

Regards
