• AD9218 interferences at L-band

    We are developing a bistatic radar using the AD9218.
    We are using the evaluation board of AD9218, and have a sampling
    frequency of 80MHz. The processing technique we use can detect
    weak signals. We have seen that the AD9218 circuit generates a…

  • AD9218: Power supply lower than specified

    Digital supply voltage is specified in table as 2.7Vmin to 3.6Vmax. But in
    several places in the text, the data sheet says the digital supply can be
    run at 2.5V. I would like to use a 2.5V Vdd supply - is it safe for me to
    do so and what voltage…

  • AD9218: using two AD9216 - Duty Cycle Stabilizer - running the two clocks 180 degree

    I want to know is whether (and why) it would cause problems if I
    run the *two* AD9216 channels with 50% duty cycle clocks 180 degrees
    apart, for interleaving purposes.

    The relevant part of the datasheet is page 22 as follows:
    The AD9216 provides…

  • AD9218 Power Supplies


    I'm wondering about the timing requirements regarding the analog and digital supplies for the AD9218.

    Can these supplies be initialized at different times? Must one come before the other if so?

    Are there any effects of supplying two different…

  • How to calculate AD9218's slope?

    Hi guys,

    We are using many AD9218BSTZ-105 chips, which are used on ADC daughter boards. Now, we are testing those ADC daughter boards performances. One of the important specification is slope. Our question about slope is how to calculate  (how to test…

  • AD9218's Vd and Ground


    1.Can i set pin 13 30 31 48 Vd(analog suooly(3v))=3.3V?

    2.Does the pin 1 12 16 27 29 32 34 45 GND have analog GND or digital GND?

  • AD9218 reference

    have a new set of ADs AD9218 in an updated design.

    the reference is measuring 1.31 V (outside the 1.25 V tolerance).   pins 5,6,7 (reference and A & B) are all tied together.  what could cause the reference to go out of tolerance
