Hi.Best ramping PLL is the ADF4159.
I want to lock ADF4159 to an external VCO. The board is set up to VCO/2 but my VCO RF output is VCO/16. Is it possible to set up ADF4159 eval board to lock with my VCO? What registers do I need to change?
We use ADF4159 and ADF5901 to produce RF signal.In ADF4159 datasheet,we can set register to set vco’s frequency,and In ADF5901 datasheet,we can set register to set vco’s frequency.the question is:if in the ADF4159+ADF5901,we set different VCO’s frequency…
I saw "AN-873" Application Note about structure of Lock Detect in PLL IC's ,I need this information about ADF4159. Is there similar Application Note for ADF4159 or Does this Application Note also applies to ADF4159?
What is the supported reference crystal input waveform for ADF4159？？
Is there any recommended 100MHz crystal type？
Can the ADF4159 be used to generate sweep triangles from 7.7 GHz to 8.8 GHz?
The data sheet for the ADF4159 specifies AIdd, DIdd, and Ip power supply currents for Fpdf = 110 MHz.
Do these scale with the Fpfd value? Is data available for the device current usage vs. Fpfd?
we set MUXOUT is DIGITAL LOCK DETECT in R0.if adf4159 is not lock,the MUXOUT is 0?similarly,if adf4159 is locked,the MUXOUT is 1?
So if i use ADF4159 with ADF5901. the R-DIVIDER and N-DIVIDER in ADF4159 and ADF5901 should be set the same.
Can you please send me the .pll file that you used for the ADF4159 loop filter...
with reference to fig 31 in the ADF5901 datasheet, is your connection to the ADF4159 similar ?
both the ADF4159 and the ADF5901 should be connected to the same…
