AD9213 Architecture related queries

Hi Ganesh_Goli,

Thank you for your interest in AD9213. In default mode (full bandwidth, M = 1), the AD9213 outputs are real.

The AD9213 has a DDC which can output complex values. When using the DDC in complex mode the outputs are complex. M = 2 (virtual converters).

Thank you.

Hi DougI ,

        In AD9213 ADC, what is the purpose of TRIG_x pin. If we want to AD9213 at 10GSps sampling rate is it necessary to use Averaged SYSREF Mode or it is only used for Multi Chip Synchronization purpose only.

Thanks in Advance

Hi,

The TRIG_x pin is used for hopping to/from different frequency profiles.

If you do not need to synchronize multiple AD9213s, you do not need to use Averaged SYSREF mode. Averaged SYSREF mode is for Multi-Chip Synchronization.

Thank you.
