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…

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。

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…

Hi,

My customer has some questions about MUXOUT state of ADF4153A before register setting.

  1. What is MUXOUT state of ADF4153A before register setting after power-on ? Please explain why

  2. Is it possible to determine if ADF4153 is defective using the a…

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…

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

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…
