Output different frequencise on AD9106

Hi,

I moved your thread to the High-Speed DACs community. Someone here will be able to assist you.

Best regards,

Thanks mcee !


Hello XINs , 

Thank you for your interest in AD9106.

Can you help clarify if you would like to generate 4 sinewaves one after the other (one channel) or simultaneously (one each channel)?

If it's the first one, the easiest way is to store DDS tuning word bit fields in SRAM. For the latter, you can load your vectors to the  on-chip 4096 × 12-bit SRAM. Since each DACx  has its own SRAM address counter  you can also set  it's separate START_ADDRx,  STOP_ADDRx and START_DELAYx. More details on pg 25-28 of the datasheet.
