• AD9258 CLOCK Generator

    Hi,

    I am using AD9528 clock module to generate a clock for the FPGA and ADRV.

    The clock which i was able to generate was 2-SYSREF-120Khz and 2-DEVCLK-245.76MHz .

    i also want to 100MHz clock output which i am not able to generate. I was able to get 100…

  • AD9258 is not getting configure?

    Dear Team,

    I hope you are doing well.....!!

    I am trying to configure AD9258 ADC using SPI, I checked the signals at resisters near to SCLK, SDIO and CSB, there i Am able get signals but while checking Vref Voltage it is showing its default value of…

  • AD9258 Design Questions

    1. I used 1.8V for AVDD power supply. Is it possible to use 3.3V power supply for DVDD? If so, what is the performance? I can see any  descriptions about it,What needs to be paid attention to in the design?

    2. I use two AD9251 chipsets to realize the output…

  • RE: 关于AD9258/AD9251的部分数据位不输出的问题

    关于AD9258,我尝试过很多方法:1、AVDD和DVDD先、后、同时上电;2、AD9517-4(为芯片提供时钟)在AD9258数字电上电前或者后提供时钟(50MHZ);3、从不同的地方购买芯片;4、控制OEB;5、在相同的电路板上测试不同的芯片;6、SPI复位;7、。。。得出的结论:好的芯片一直都是好的,不好的芯片这么折腾都不行(这些芯片里面有的是没有DCO输出,有的是有些数据位不输出)。这颗芯片到底是对什么地方要求高呢,,,,

  • Inquiry about the design of the AD9258 and the ADA4937-1

    Hello,

    My customer will use ADA4937-1 and AD9258 at repeater application.

    1. Input voltage range of the Vocm pin in the ADA4937-1 is min 1.2V to max 3.8V. However, the VCM output of the AD9258 is 0.9V.

        The voltage ranges between the Vocm pin and the…

  • RE: Request Schematic review with ADA4939-1 and AD9258-125

    Hello,

    A few comments pertaining to the AD9258.

    • Looking through schematic, I would suggest using the DCOA and DCOB signals since this is meant to be the latching signal for FPGA's input receiver.  One can connect this signal to one of the unused…
  • Start-up question about your AD9258

    Dear Sir/Madam,

    Our customer asked following question for your AD9528.

    Will the register setting be set-uped automatically after power-on from external EEPROM via SPI/I2C ?
    Also the EEPROM have the default value.

    Thanks Kaos

  • About AD9269 and AD9258 footprint data problem

    Flowing picture is the AD9258 and AD9269 footprint data, as discribed in the datasheet, AD9258 and AD9269 is pin compatible.But, the blue circle sign in the picture,  the data may be wrong?Thanks!
