    Hi,
    

    If I simulate the AD9641 using Virtual Eval, I can choose between two speed grades: 125 and 130 MHz.
    

    However, the component's datasheet speaks of 80 and 155 MSPS.
    

    The noise performance reported in the datasheet is different from that obtained using Virtual Eval (72 dBFS vs 76 dBFS).
    

    Which value is the most reliable?
    

    Is the AD9641 a good candidate for a single channel design?
    

    I'm looking for a NSD better than -156 dBFS/Hz at 100MHz input frequency.
    

    Could you please recommend the most suitable part?
    

    Thanks
