CC1200 PLL

Other Parts Discussed in Thread: CC1200

Dear Support team,

We are trying to get unmodulated carrier frequency from CC1200 output. Registers values are taken from Smart RF Studio. Cause we have not evaluation board, we are exporting the registers values from SmartRF and configuring via our designed  device using that file.

Problem: We still can`t see carrier frequency. It must be 868MHz, but on analyzer screen we can see only floating 760,56Mhz, we assume it`s VCOs minimal freq and PLL is not locked. The output power is what we are configuring.

Note:  We have 2 chips, for both result is the same

What is the reason ?

Can you send us working configuration and command sequence.

Thanks in advance !
