CC1352R: Unable to configure all Sub1GHz frequency bands in CCS

Hi Jack,

This is due to the fact that we do not have a characterized PHY in that frequency band for the device. You mention this frequency band as an example. Are you trying to use it in your application or is there another frequency band you are actually interested in using? Do you have information you could share about the PHY you would like to use?

Hello Diego,

We require the use of the following bands for our products (RX only):

• 287-351 for nominal 315MHz
• 359-439 or 431-527 for nominal 433MHz
• 861-1054 for RF monitoring

We would also require the use of the 2.4GHz radio for OOK TX only, without any stack such as BLE.

When do you expect the use of the remaining advertised frequency bands to be available?

Many Thanks,

Jack

Hi Jack,

In SmartRF Studio you can find multiple PHYs that have been characterized for 431-527 MHz and 779-930 MHz band. For 287-351 MHz band we don't have a characterized PHY, although the synthesizer has been tested to operate in this frequency band.

what type of signals are you trying to receive in the non 2.4GHz bands? Are they also OOK or are they 2GFSK?  What is the symbol rate, and if using 2GFSK the deviation?

What is the symbol rate of the 2.4GHz OOK PHY?

Hi Diego,

How can we use the 287-351 MHz band in CCS? Do you know when it will be available?

At 315 and 433MHz the symbol rate could be up to 19,200 baud and either OOK or 2FSK.

For 2.4GHz, we currently cannot share any details on this. 

For reference, we currently use the CC1101 on our products and require use of the 2.4GHz radio in the future so were looking at the CC1352 as a combined device. We would likely be looking to use the CC1352 in a similar manner, that is configure the RF and allow a data stream back to a separate device.

Thanks,

Jack

Hi Jack,

Regarding PHY settings:

• The best approach would be to use SmartRF Studio 7 to find the appropriate PHY settings, see the following App Note for guidance: SWRA682 (Finding Settings for new PHYs for the CC13x0 and CC13x2 Family): https://www.ti.com/lit/swra682
• Then export the settings from SmartRF Studio 7 to use in CSS: https://dev.ti.com/tirex/explore/content/simplelink_cc13xx_cc26xx_sdk_8_31_00_11/docs/proprietary-rf/proprietary-rf-users-guide/rf-core/phy-configuration.html?highlight=smartrf%20studio#phy-configuration

If it's a large opportunity, please contact your local TI Sales about this.

Regards,
