Request for Target impedance values for powers of Agilex5 E-Series SoC FPGA(Agilex_A5ED065B B32A)

Hi

We are performing PDN analysis for checking if the impedance targets are met for CPU (Agilex_A5ED065B B32A) powers.

Please provide the Target impedance values over frequency for all the powers. The tool used is Ansys SIwave

Thanks and regards,

Chaithra K S

    Hello,

    Before proceeding with this request. Can you please clarify what do you mean by the Impedance Value over frequency.


    Best regards,

      Hi,

      We are optimizing the PDN by trying to minimize the capacitors used as well as the placement of capacitors in the board. As we are designing high speed board this is crucial for us. So, we need to understand the range of impedance required for all the CPU core powers so that we can optimize the design.

      we are expecting the impedance values over frequencies for CPU powers. So please provide us the target impedance ranges with respect to specific frequencies.

      Thank You.

    Hello,


    Sorry for the delay. For this request, we recommend that can use AN984 to design the coupling solution.


    Hope that answers your question.
