• Can AD9763's NC pins (i.e. pin 33 & 34) be driven or must they be definitely left floating?

    Can AD9763's NC pins (i.e. pin 33 & 34) be driven or must they be definitely
    left floating?
    We have the option to fit the AD9763 or the AD9765 on the same board. When the
    AD9763 is fitted the DB0 & DB1 N/C pins (i.e. pins 33 and 34) are…

  • RE: AD9763 AD9765 AD9767 Interleaved mode with 125 MSPS update rate possible?


    Apologies for the delayed response. 

    The t_h specified in table 3 should be the hold time for rising edge of WRT and the data in (Please refer to figure 2). This does not specify the t_h* shown in figure 64 but rather shows that IQSEL should…

  • RE: AD9763 digital inputs threshold


    Please refer to Rev G of the datasheet.

    The minimum Logic 1 value is the minimum input voltage at the logic pin for the device to recognize it as logic 1 or high.
    2.1 V is the minimum value. 3 V is the typical value.

    Vthreshold is approximate and is not…

  • RE: AD9763 output state on power up

    Yes, until a clock is applied, the output is indeterminate.

  • With regards to AD9763

    Hi ,

    Could you please let me know the –40°C to +85°C as Operating temperature same as Case temperature (Tcase) or is it Ambient Temperature.

    Could you please let me know if there is any data with regards ThetaJC .

    Thanking you

    With best regards and…

    About AD9763.

    Can you tell me what I should do about unused pins if I use port1 only ?
    Unused pins are CLK2/IQRESET,WRT2/IQSEL,DB0-P2~DB9-P2/MSB,IOUTA2 and IOUTB2.
    Connecting to ground, power supply, or nothing?
    What should I do more except these?

  • AD9761 and AD9763

    Are these parts obsolete or near end of life?

  • TxDAC Two Singles vs. One Dual

    I'm adapting a design from a retired engineer with two discrete AD9705s being used for IQ modulation. I noticed that in an earlier design, he had used a single AD9763. Comparing both of these options, it seems that the two discrete AD9705s beat the AD9763…
