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…
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…
The latest ADF4153, ADF4153A, ADF4154, ADF4156 and ADF4157 evaluation board software is attached.
Windows XP, Vista, 7 compatible.
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…
Improved PLL 1/f noise:
120dBc/Hz @ 10kHz offset for RF = 1GHz for ADF4153A
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
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…
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…
