• How to set LTC5586 ADRF6520 AD9691 Common mode voltages ?

    Dear Sir,
    Our application is Zero-IF.
    But AD9691 provide common mode voltage 0.85V.
    I have some questions as below:
    1. What the common mode voltage for ac-coupled of ADRF6520?
    2. May I use  AC-coupled connection from LTC5586 to ADRF6520 and from ADRF6520…
  • AD9691 and AD9691 evaluation kits (AD9691-1250EBZ)?

    Is there any user guide of AD9691 and AD9691 evaluation kits (AD9691-1250EBZ)? I cannot find the information in the website. 

  • RE: AD9691: Power-Up sequence for supplies needed?


    There is no power-up sequence required for the AD9691. There is an internal power on reset (POR) circuit that holds the AD9691 in a reset mode until all the supplies are at their required level. Once all the supplies are at their required levels…

  • AD9691 max. sampling rate??

    Hi concerned...

    I'm looking for multi-channel & high speed ADC(above 1Gsps).

    Finally I found a part(AD9691-1250) that meets our requirements.

    I want to use AD9691 ADC at about 1.5Gsps, but its' max. sampling rate is 1.25Gsps on datasheet.…

  • What is the max. JEDS204B lane rate of AD9691?


    I have some confusion about contents of the max. JESD204B lane rate in AD9691 datasheet.

    As Page 43 of AD9691 datasheet, it seems to be up to 10Gbps.

    But as Fig.78 ,Fig. 79 ,Table 26 and Table 25 in AD9691 datasheet, it seems to be up to 12…

  • RE: AD9691: Driving SYNCINB Input single-ended

    Hi Gerald,

    When running SYNCINB± in CMOS mode, connect the CMOS SYNCINB signal to Pin 26 (SYNCINB+) and leave Pin 25 (SYNCINB−) floating.

    Thank you for pointing this lack of information out to me. The AD9680 is the four JESD204B lane version of the…

  • Question about AD9691 in Complex output mode


    My customer use AD9691 and they confirm the normal output at DDC Bypass (Real Output) mode.
