10 years later, have a follow up question to the above!
Am using divout and do indeed need to band pass filter the signal due to some spurs coming from intermodulation between the reference clock and the VCO, so knowing the actual output impedance of…
How do we come to know that whether the synthesiser ADf4360-9 has been programmed properly or not...
Hello Vladimir,
Reference spectral purity requirement will depend on the application as the noise of the reference inside the loop is not attenuated, but is well attenuated outside the loop bandwidth. We dont spec it.
Check the spectral purity of your…
There is an alternative solution where you just use the ADF4360-9 on its own.
If you connect your 2 MHz signal as the ADF4360-9's reference and program the DivOut pin to output a divided VCO output signal. For example, you can lock the VCO to 360 MHz…
Does anybody know about the Phase Comparator of ADF4360-9
- gain? "Kd"
- Maximum amplitud of detection? "A"
and about the VCO of ADF4360-9
- free oscilation frequency?" Ff"
Hi,
I've read ADF4002 and ADF4360-9,ADF4002 is more complicated in my oppinion,I have to build the external loop filter and VCO if I use ADF4002,but it's a very truble thing to pick up these parameters.So I decide to use ADF4360-9 to test first.…
Hello,
Yes, the DIVOUT is not very well specified…
If you look at the signal swings on page 9, in fig 12, the swing from high to low is greater than the required 1.2Volts, but the duty cycle is only 45%, therefore , if the application requires the…
First question:
We are running the ADF4360-9 beyond the published temperature specs. The circuit has been run up to 125 degrees C and appears to work fine for our application. Do you have any information as to the long term effects of operating the ADF4360…
