• RE: LTC3405A

    Type II compensation is not a must. For the bandwidth, it's also related with the system parameter. We recommend a direct test  on your designed system and decide whether adding Type II can give you a desired stability margin.

  • RE: 关于LTC2217 手册中关于差分输入范围的描述:2.75Vpp

    谢谢,那当共模电压为0时(当然LTC2217可能是1.57),我的输入信号范围AIN+-AIN-的范围在-1.375V至1.375V之内?还是AIN+单端的范围在-1.375至1.375之内呢?

  • AD9517-3 on-chip VCO

    Hello,

    We are using AD9517-3 on-chip VCO working at 2048MHz with a 10MHz reference.

    Following the ADIsimCLK ("Frecuency Tune Dialog") the VCO tuning voltage

    should be around 1.375. But we get 1.68 in some boards and 1.29 in others

    In this…

  • Alias Frequencies

    I'd like a sine wave of 2.375 GHz, so the plan is to generate 375 MHz but as
    the sample rate is 1 Gsps, the aliases will appear at 625 MHz, 1.375 GHz, 1.625
    GHz, 2.375 GHz 2.625 GHz and so on.

    Can the DACs available achieve these…
  • RE: What is the frequency of the ring oscilator for lock detect in the HMC765?

    We tried your settings, and it did not work.  My original thought was that  = 0b  was 21 per the table with a divide by of four, yielding 5.5 nsec.

    I am thinking this did not work because it this actually sets the lock window to 21 nsec, and should be 5…

  • LT4363 timer current and fault timing calculation.

    Application and Circuit Description

    We are using the LT4363-2 as an overvoltage and overcurrent protector in our products.

    The design calculation and simulated values do not agree and hence want to confirm whether my calculations are correct. I suspect…

  • RE: HMC749 cml fpga

    Hi,

    AC coupling can be used but the value of the capacitance should be consistent with the lowest frequency content of your signal. If the signal has lower components than a practical capacitor level, DC coupling should be followed. Please see the application…

  • RE: HMC746 FPGA kintex 7 xc7k325t_900

    What is the interface standard you have on your FPGA? Is it LVDS, ECL or similar? What is the reference voltage, 1.8, 2.5, 3.3, 5 ? We can figure out the interface if you could tell us the interface standard, the swing, and the termination voltage.

    Please…
