• ADF4153A Programming question

    Hello,

    I had a question about how to program registers 2 and 3. The data sheet say "Data is clocked into the 24-bit shift register on each rising edge of CLK."

    R0 and R1 are 24 bits long. Programming those two registers seems straight forward…

  • ADF4153A做PLL进行跳频,Vtune上出现毛刺

    黄色为Vtune电压,蓝色为MUXOUT锁定指示。

    如图所示,黄色尖状毛刺出现时,未锁定。

    请问是,ADF4153A器件原因造成的随机性不锁定现象嘛?并且会在不锁定的时刻出现毛刺。

  • What is the purpose of RFinB in ADF4153A PLL ?

    Hello, I would like to know the differences between RFinA and RFinB input in the ADF4153A PLL.

    I've read that RFinB must be grounded (via a bypass capacitor) when using single-ended applicaiton but I don't understand what it means.

    Is it possible…

  • RE: MUXOUT pin state of ADF4153A

    MUXOUT comes up in a high impedance state until it is programmed to another one.

    MUXOUT can be used to check if the R divider, N divider and digital logic are all working effectively (assuming they are correctly connected in hardware, and properly programmed…

  • ADF4153A failure in power on-off test

    Hello,

    My customer is using ADF4153A as the following conditions:

        REF_IN: 10MHz / External_VCO: 608MHz / PFD_freq: 5MHz / CH spc.:500KHz

    There is no problems in a normal state.

    When the customer test the repeated power on-off, ADF4153A is occurred…

  • ADF4153 Vs ADF4153A

    Hello

    Can you advise what are the differences between ADF4153 & ADF4153A?

    These parts are functional & pin to pin compatible, however the package looks a bit different.

    The SW is also the same.

    Are the difference performance wise?

    Thanks

  • ADF4153A Refin type

    Possibly a basic questions but I'm trying to determine the type of clock I can use for the Refin on an ADF4153A.  The data sheets states that it is a CMOS input or AC coupled with threshold of VDD/2.  if my VDD is 3V can I run this with an AC-coupled…

  • RE: Tunable Bandpass filter for the AD8362 input

    Hi,

    Following your design idea, and to keep the cost down, as im only looking for the presence of the signals and nothing more, could i use a

    ADF4153A or ADF4350

    ADL5350

    and a ADL5501?
