AFE7444EVM: Sample rate Setting optimization

Ryan Lee TW
Intellectual 696 points

Part Number: AFE7444EVM

Hi teams,

My customer is using AFE7444EVM to evaluate the performance.

Please recommend the ADC/DAC sample rate which applied in the frequency of 2.9~3.5GHz, and other linkage settings value.

The performance of output result is not so good due to using 122.88M which is the default value of EVM.  

Thanks.

    Hi Ryan,

    For this band, ADC sample rate close to 3GSPS (2.94912 GSPS with EVM on-board clocking) can't be used. As 2nd and 3rd Nyquist boundary is within this band. Your customer can instead use ADC sample rate close to 2.25GSPS (2.21184 GSPS with EVM on-board clocking)

    DAC sample rate of 9GSPS (8.84736 GSPS with EVM on-board clocking) can be used. 

    Mode 8 from GUI can be selected for this.

    Regards,

    Vijay
