• 关于ADRF6612

    在使用时发现该芯片有如下问题:

    1.脉冲调制信号输入功率较大时,输出信号在下降沿结束后仍然有一段时间的托尾现象,如下图圆圈所示.

    2.当输入到芯片的射频信号功率较大时(约大于0dbm),芯片内部锁相环会失锁。

    请问这个什么原因,请回答,谢谢。

  • ADRF6612 GSM VCO frequency range

    Hi,

    What is the frequency range of the GSMVCO_0 (HB, 3.5GHz) and GSMVCO_2 (LB, 2.22GHz) in the ADRF6612 ?

    Thanks for your kind help and support.

    Best regards.

  • ADRF6612寄存器配置

    1:关于ADRF6612,按照官网上的软件生成了寄存器值,但是写入后,PLL无法锁定,参照datasheet,这个寄存器配置有顺序要求,其中寄存器2,3,4必须最后写入,这里不明白的是,这2,3,4之间是否还有顺序要求?

         或者其他寄存器配置也有严格的顺序要求?

    2:另外ADRF6612有几个只读寄存器,在SPI读操作时,读出来的数据与datasheet上的不一样,差异比较大,不知是何原因,因为另外几个可读写寄存器写入与读取的数据可以对上,唯独那个几个只读寄存器不行。

  • 关于ADRF6612请帮忙解答,谢谢。

    您好,我第一次用这个芯片,还有几个问题如下,请帮忙回答:

    1.手册第4页说 Reference Divider Value Programmable to 0.5, 1, 2, 3, …, 2047 ,而第31页说The reference path takes in a reference clock and divides it by a factor of 1 to 8191,那参考路径的分频到底是多少呢?

     

    2.关于寄存器10中 [13:12] IFA_LINSLOPE和[11:10…

  • How do I enter loop filter components from the ADRF6612 eval board into ADISimPLL?

    I want to simulate the ADRF6612 eval board in ADISimPLL. How do I enter loop filter components from the ADRF6612 eval board into ADISimPLL? When configuring ADISimPLL with the ADRF6612 as the chosen device, I do not see a means to enter loop filter components…

  • when the pll in adrf6612 is locked the muxout level is high or low?

    when the pll in adrf6612 is locked the muxout level is high or low?

    adrf6612内部锁相环锁定后,muxout管脚是高电平还是低电平啊? 手册给出是高电平是代表锁定,但是我的板子测试时是低电平锁定,请帮忙解答,谢谢。

  • 请帮忙提供一份ADRF6612的寄存器设置,谢谢。

    第一次使用这个芯片里,里面好多寄存器不知道如何设置,请帮忙提供一份ADRF6612的寄存器设置,我使用的是他内部的本振电路。(注明参考及鉴相频率、输出频率等信息),谢谢。

  • RE: ADRF6620 EVAL board and software issue

    Hi Cindy,

    It seems like you are using ADRF6612 evaluation software. Although these are similar products, I would advise you to download the ADRF6620 customer eval software (http://www.analog.com/en/products/rf-microwave/mixers/rf-mixers-w-integrated…
