AFE7901: Sample 4 channels with 2 x 125 MHz (2 DDCs) each

Part Number: AFE7901

Tool/software:

Team,

is it possible to sample 4 channels with 2 x 125 MHz (2 DDCs) each?

The datasheet mentions IBW of 400 MHz.
2 x 125 MHz = 250 MHz < 400 MHz
Can you confirm this?

Best regards

    Hi Franziskus,

    You mean, using 4 Rx channels with 2 DDCs each to capture two 125MHz wide signals?

    If yes, the AFE7901 can be configured with an output rate of 187.5MSPS with 2 DDCs per Rx chain. So this would be able to capture the two 125MHz wide signals per chain.

    Best,

    Camilo
