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…
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…
可以考虑ADF4153A

Hello Ross,
Yes, you can run REFIN with an ac coupled sinewave at 10Mhz....we recommend keeping the slew rate greater than 25V/us, using a REFIN of 10Mhz with a pp of 2Volts , is well within 25V/us.
The choice between the DC-coupled, CMOS compatible…
Hello Alan,
Improved PLL 1/f noise:
120dBc/Hz @ 10kHz offset for RF = 1GHz for ADF4153A
Compared to
114dBc/Hz @ 10kHz offset for RF = 1GHz for ADF4153
Improved PLL FOM -222.5dBc/Hz vs. -220 dBc/Hz.
Improved spurious performance -76dBc vs. …
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?
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…
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。
The prescaler is needed to divide down the RF input to a frequency that the rest of the N divider can handle. The prescaler either divides by 8 or 9 depending on what is needed. This is all taken care of internally.
ADF4116 is an integer-N PLL so it…
