  • AD9634 digital signal rippling interference

    Hi, I am using AD9634.When I use the test mode and use ramp out,  I observed some glitches. as shown in the first feagure.

    then I use a oscilloscope to check the digital signals, I I observed that, the digital signal from the scope looks wierd. it is supposed…

  • AD9634 HDL and linux device-driver sources

    Hi

    I have designed and assembled an expansion board of the AD9634 250MSPS ADC to the Avnet Microzed Zynq-7020 FPGA evaluation kit, I have followed all recommendations on signal integrity and clocking requirements.

    I am now looking for both HDL and linux…

  • SESSION_MANAGER environment variable not defined - AD9634

    Not sure why I am getting the below error from the example. Should not all the env variables be pre set? or is there another issue at hand?

    I wanted to run a simple test with the board before jumping into a BPSK example.

    Please let me know if things look…

  • AD9634 PN9 Test

    I set several test mode of AD9634, and get samples from FPGA as shown below.

    I think the three mode(one/zero word toggle, alternating checkerboard, ramp output) are passed. But for PN9 test, there are two zero word. I'm confused. Can someone tell me…

  • AD9634 TEST MODE

    I will use test mode.

    Could you tell me designation method of the user test mode 1-4?

  • AD9634 drift specification

    Hello

    Our customer uses AD9634 then ask internal reference drift pecification but describes its specification in the datasheet.

    Datasheet describes about the drift spec of gain error and offset error.

    I understand that these  two speficiation (TYP)   are…

  • AD9634 Differential input voltage Spec of CLK

    Hello

    AD9634 datasheet Figure 55  uses AD9510 for clock driver of  LVDS.

    The differential input voltage spec of AD9634 is  0.3V ~ 3.6Vp-p.

    The differential output voltage of AD9510 is 250mV~450mV.

    Out customer  asks if AD9510 does not meet input specification…
