  • AD9643 registers


    In revision D of AD9643 the BIST enable register 0x0E is not given but in Revision B it was given. So is there any other setting that is used for starting the bist ? How to enable this feature ?



  • AD9643

    AD9643 have two  pin configurations, Parallel LVDS  and  Multiplexed (Even/Odd) LVDS; Which one do AD9643BCPZ-250 belong to?

    The analog input of ad9643 evaluation board is a 1:1 transformer. Is the differential line impedance from the transformer to the chip end controlled as differential 50 ohms in PCB design? But looking at the Gerber file of the evaluation board, it seems…

    i am working on AD9643 ADC, i am not able to do the data output from this fro different input voltages as per the table11 given in datasheet.

    i used a formula

    DATAin decimal=(applied input volatge*2^14)/1.75

    am getting

  • sync multi AD9643

     I am using two dual channel adc ad9643. I want know how to use SYNC pin of those ADC to synchronize  ADC data output . Sampling clk for all adc is same and generated from a single crystal oscillator( same source). 

     Sampling clk is 200MHz , clock divider…

  • RE: about AD9643 Ibis

    the ibis models seem to be generated pretty conservatively. try using a scope probe on the eval board, it would be better.
