CC3135: RF coex signals

Hi,

The Coex signals would need to be connected to the CC1354 device. Here is an app note that covers this in more detail.

Hi Dylan,

It seems the link does not work (404).

Hi Peter,

Just remove dot from end of URL - https://www.ti.com/lit/an/swra608a/swra608a.pdf

Thanks Jan.

Peter I have modified the post (adding hyperlink) which should fix the linking issue.

Hi Dylan Hubbard, 

In the shared document the analyzed example is with bluethooth, in my case I have zigbee with CC1354.

Does it work the same with zegbee?

In the BOOSTXL-CC3135, the signal CC_COEX_SW_OUT in which is used?

Hi,

It should work for any 2.4Ghz protocol, the main thing to is to follow the guidance in section 2.2 of that app note. The CC3135 device shouldn't care whether its BLE or Zigbee as long as the Coexistence I/O are operated accordingly.

Could you clarify your question a little more or reword it, I'm having trouble understanding it.

Hi Dylan Hubbard, 

Sincerely Thanks very much.

In the BOOSTXL-CC3135 design, what is the CC_COEX_SW_OUT signal used for?  I show the signal in the image below.

Let me ask another question, please. I see that in the BOOSTXL-CC3135 design to control the 5GHz switch they use SOP0 and SOP1 instead of standard GPIO. Would it be ok to use SOP0 and SOP1 in the coexistence diagram I show?

Thanks very much
