FCC Certification Considerations¶
CC1312PSIP FCC Module Certification¶
In order to re-use the FCC RF Module certification of CC1312PSIP on Sub 1GHz channels, an application using TI 15.4 stack (in Frequency Hopping mode) or TI Wi-SUN FAN stack needs to limit the transmit power to the following values. If you set the transmit power to more than the values stated in the following tables, you need to re-certify the product and will likely pass only with duty cycling.

Additional Condition |
TI 15.4 Stack |
19 dBm |
If you only use channels between 908.2-927MHz |
TI 15.4 Stack |
16 dBm |
If you include any channel between 902.2-908MHz |

If you duty cycle with 60ms out of 100ms in TX |
TI Wi-SUN FAN Stack |
17 dBm |
Without duty cycling |
If you are using other certified PHYs, you will find the limits in the following tables.

If you are using the 14 dBm port, the following table provides the maximum TX power that you can set during transmission in order to re-use the FCC RF Module certification of CC1312PSIP on Sub 1GHz channels. It is not necessary to use duty cycling or modify channel plans in this case.
