CC1352P: What is the LO/VCO frequency for sub-1G uplink/downlink inside cc1352p1

Part Number: CC1352P

Hi Sir,

We have some EMI issue on 456 MHz and would like to know:

1. RF LO frequency is low IF architecture or direct down/up architecture, by which its LO = ?

2. Is there any clock or processor running on 456MHz or its divided by N ratio (N is integer)?

Thanks

Wilson

    None of the questions seems relevant for your issue, meaning that we don't have an internal frequency that could explain what you are seeing. 

    - Which frequency are you sending on? Does the spur move when you move the carrier?

    - Is this measured on a custom board? If so, do you see the same on a Launchpad with the same settings? 

    - Please provide a plot with markers that clearly show the spur frequency, the signal strength and the delta to the fundamental. 

    - Is this just an radiated issue or are you also seeing this on conducted measurements?
