Dear Srs.
We start the project with ADF4159.We send data to registers through SPI as in datasheet.
DC regimes and levels are Ok.
But we failed to read anything on maxout.
What we are doing wrong?
Thanks'

We have resistors only on SPI as it mentioned n the evolution board. We will try lower frequencies. We program serial output ( 0111) on muxout.
When we programed N divider (0x3) then on muxout we have no waveform, when we program Ndevider/2 (0xE) we receive picture with saw form - 1,5 V - picture P1. Frequency is correct.
On output of R divider…
Hi, we have fined non soldered leg! Chip is working now.

On output of R divider we have signal 0,7V shifted up on 0,8V - picture 2
We do not have locked loop.
