AFE7900: Limitations when using both DDCs?

franziskus

Part Number: AFE7900

Team,

the AFE7900 has two DDCs per ADC channel. Are there any limitations when both DDCs are used, such as limitations to decimation rate or NCO frequencies?

Thanks and best regards

Hi Franziskus,

In datasheet Table 8-5, The non-grey boxes have 2 DDCs, while the grey boxes have 1 DDC only.

And both DDC bands should be in the same Nyquist zone.

Regards,

Vijay
