ADF4118 support

The evaluation board control software is very similar.

Many thanks fory your quick answer.

I got also this nice tool

I got error in formating number

Sorry it is in French "input format is incorrect" last sentence .. I think it is the

separator story xx.yy or xx,yy i will check that point

most important is ; we do not get the Initialisation Latch value with this software

this was not the case with the online version.

thanks for the job done

I'm pretty sure the separator is the problem. If it isn't, let me know and I'll fix it.

The Initialization Latch is the Function Latch + 1. i.e. the data bits are the same, only the control bits are different. If Function = 0x8008A, Initialization = 8008B.

Hello

you are completely Right on the two subject !

sorry I didn't check the Function and the Init latch values ..

let go for fun now ..

Thanks

Francois

Sorry, just one thing

in version 7.4.3 the window size of the "B" must be bigger

see the hard copy

There seems to be a different bug in that screenshot.

The ADF4118 only has a 32/33 prescaler, but the P box is showing 8. Is the ADF4118 selected on the 'Select Device and Connection' tab? If so, do you know what part you had selected before the ADF4118?

My good, you see all my errors !

I don't know why the value 8 was selected !

I relaunch the ADI N software v.7.4.3

the prescaler was 8 ... I select ADF4110 and after ADF4118 and I see value 32

As I remember, I started last time ... I select 4118 .. I enter 2176 Mhz ... 10 Mhz ..10 Khz  as RF setting, BUT I didn't check if prescaler was 32 !

so I don't know what happens ..

thank for your great help

If you're happy, please mark this question answered.

Hello

It is not finish today.

I use my old Arduino test software (for ADF4110) to send the values in the latches

for the moment, Pll is not locked.

I have a question :

Latches are 21 bits long, I have three solutions:

1/ in a loop sequence, check only the 21 bits and send ONE or ZERO (quite long)

2/ send Three bytes

3/ use a long word (32 bits) and send it

on the datasheet (file joined here) on last page (20) there are Two examples

and they send 24 bits ...so I understand that we can send as long we want, only the last 21 bits will be stored at LE high time

Am I right ? if yes I will use option 3 ..

regards,

Francois

Are you using the ADF4110 or ADF4118?

The ADF4110 has 24-bit registers.

The ADF4118 has 21-bit registers.

Correct; once LE goes high, the most recent 24 or 21 bits are taken and the rest are ignored. Option 3 should work.

If it doesn't work, please post the register values you are sending below.
