Supported frequency on CC1310

Nomo

Other Parts Discussed in Thread: CC1310

Hello,

Please let me know whether CC1310 can support 426MHz and 429MHz.
From the datasheet, 433-MHz ISM and SRD Systems can be supported.

Best Regards,

Nomoto

Yes, 426/ 429 MHz is supported. Currently we only have a preliminary reference design for 433 MHz meaning that we only have done very limited amount of measurements in this frequency band.

could we release the 433MHz reference design to customer?

The 433 MHz ref design is still preliminary but as the measurements show the performance looks good.

Hi TER,

Any chance to get this design?

Igor, not sure if I understand your question? The preliminary ref design is attached to my previous post.

Ohh, I see it now.
The link with preliminary test is concatenated to the link with ref des.

Thanks anyway.

Hi TER,

In the reference design you've attached in your previous post, the info in the Readme file and the writing on the silk layer says it's a 425MHz design, is it ok?

I was comparing the antenna with this design (you've mentioned it in another thread) and it seems ok.

However, I want to be 100% sure this design is suitable for 433MHz.

Another thing, is there any planning on a 4 layers cc1310-433MHz design with a PCB antenna?

Thank you in advance.

Our naming convention for the CC1310 EMs is a bit confusing. In one of the many tools required to get things out on the web it's a limitation on the numbers of letters (don't ask me why...) hence the reference designs has a 4 digit frequency code. 4251 actually means that the design can be used from 420 MHz to 510 MHz.

It's likely that we are going to make a CC1310 with 433 MHz PCB antenna but nothing planned shortterm.

hi TER

I see "CC1310 433 MHz Preliminary Performance Figures" document,it menthioned that RX sensitivity is -110.2dBm.But my testing is -108dBm, based on our own board,and the condition is simply as same as yours.

I wonder that how did you test?Our test is Using SmartRF studio 7,modify frequency from 868M to 433M, and packet RX, Observing the "Average RSSI Value". when BER > 0.1%, we consider it as a bad transmit.

Is it correct?

Thanks!

We use 3 byte payload and 20 % PER which correspond to 1 % BER. If you use 0.1 % BER the sensitivity will be somewhat higher.
