Request the schematic review with AD9251-80 and ADA4937-1

Hi,

My customer wnats to get your advice about their schematic with AD9251-80 and ADA4937-1.

They used AD9251-65 and ADA4937-1 in their system, but now they will change the sampling frequency of their system.

So they need your help.

The sampling frequency that they want to use is 76MHz and IF is between 47.5MHz and 95MHz.

And their target application is LTE ICS repeater.

Would you confirm their schematic with AD9251-80 and ADA4937-1 ASAP?

Regards,

Se-woong

  • Hi, Doug

    Thank you for your kind help.

    Actually they want to use the same schematic as the one that was used before for the AD9251-65.

    So they want to get your confirmation for using same schematic even though the sampling rate of AD9512 is increased from 65MSPS to 80 MSPS.

    Regards,

    PS. Their ICS repeaters already deployed to commertial LTE networks in Korea several years ago.
