ADF4371 RF16 configuration

Hi Goli,

You need to set the fundamental VCO frequency as it is described in the datasheet and enable the RF16 output by setting Reg0x25[3]=1.

You can use the ACE software to generate register settings for ADF4371. 

Also, we have a Linux driver which can be reached with the link given below.

They should be sufficient to program the part.

Hi Goli,

Can you direct me to the driver that you mentioned? I am not very familiar with drivers but I can give it a look to understand what "num" stands for. Thanks.

Hii kudret.unal ,

                                    Actually I want to build a driver for AD9213 with VCU118. Since for AD9213(10.25 GSPS ADC) we could not find any no_os files. In the AD9213 schematic it shows hmc7044 configures the ADF4371 PLL such that it produces a clock for ADC. Here I'm taking AD9081 as reference for ADF4371 PLL configuration. I'm attaching the link below for that.

line no : 310

Here I'm also attaching ADF4371.c soure code.

Thanks in Advance

Hi Goli,

I think num=2 refers to RF16 channel given the fact that freq is 12 GHz, assumption make sense. 

clkin_freq is the reference frequency that you are providing to the ADF4371 REFIN input. 

To get more details on driver usage, you can post your question toLinux Software Drivers - EngineerZone (analog.com).
