• Using HMC832 as a Vco

    Hi, I have a question, Is it possible to use only the HMC83x's  VCO as a VCO in another pll structure? Does this require special requirements?

  • Instability of the signal initial phase at the output of HMC832

    Hi!

    I tuned the chip HMC832 on EV1HMC832ALP6G evaluation PCB  to generate a 50MHz signal and applied a 50MHz sync signal from generator based on direct digital synthesis of signals at the input of this evaluation PCB. HMC832 provided synchronization of the…

  • HMC832 differential output mode

    Hi,

    We are planning to use the differential outputs of HMC832.

    It will be beneficial to use the common mode rejection of the output.

    Should I use a transformer/balun for converting it to single ended, since I'm driving a single ended 50Ohm load.

  • HMC832小数模式设置问题

    最近在使用HMC832芯片时发生了如下问题,希望能解决。

    在设置HMC832芯片时,整数模式设置正常,小数模式不论设置输出频率是多少实际的输出频率一直 在3Ghz左右。

    使用的输入频率为50Mhz,寄存器参数设置如下

    整数模式:

    hmc832_writeReg(0x01, 0x03); 
    hmc832_writeReg(0x02, 0x01);
    hmc832_writeReg(0x05, 0x90); 
    hmc832_writeReg(0x05, 0x4F98); 
    hmc832_writeReg(0x05…

  • HMC832小数模式设置问题

    在使用HMC832芯片时遇到了如下问题,百思不得其解,希望有人能为我解惑,谢谢。

    在配置寄存器参数的时候,分别使用整数模式和小数模式进行配置,整数寄存器配置完成后输出频率正常,小数寄存器配置完毕后输出的频率一直在3Ghz左右。

    输入的频率为50Mhz,寄存器参数配置如下:

    整数模式:

    hmc832_writeReg(0x01, 0x03); 
    hmc832_writeReg(0x02, 0x01);
    hmc832_writeReg(0x05, 0x90);

  • HMC832 LD time issue?

    Dear Sir:

                     For HMC832, Can we use VTUNE pin to measure time of lock detect? We measure some swing through VTUNE pin.   If it can't  to do , How to evaluation LD time? BTW , HMC832 's LD time is fast than ADF4351? Thanks.
