What effect does noise on the Vvco line have on the PLL output. Do we have a spec, similar to PSRR?
How stable are the VCO output levels over temp. for the ADF4360-8 and the ADF4360-4?
I have two ADF4360 that are generating two different frequencies from the same 10MHz references. Device #1 generates 800MHz while #2, 1800MHz.
As you can see, 1800MHz is not an integer multiple of 800MHz. However, there are exactly 9 1800MHz…
The latest ADF4360-x software is attached. This is compatible with all the ADF4360 family.
1. Disconnect any evaluation board
2. Download and run the attached installer

See Figure 32 on page 25 of the ADF4360-7 datasheet. This should answer your questions.

I have got the output like this, but I do not know the reason, the lock pin signed be locked, have anyone know what is the problem? The output frequency is right , but the power is not lower than the setting.
On the ADF4360, all the registers are 24-bits. The firmware will actually send 32 bits, but the first 8 will be ignored by the ADF4360.
If I do not need the differential outputs on the ADF4360-8, do I only use 50 ohm resistor to terminate the unused output? or i still need to add output matching circuit on unused output.(as Figure 28. Optimum ADF4360-8 Output Stage on datasheet).Thanks…
