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.

Table 14. Power Limits for TI 15.4 stack on 20 dBm PA

Stack	Tx Power	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

Table 15. Power Limits for TI Wi-SUN FAN Stack on 20 dBm PA

Stack	Tx Power	Additional Condition
TI Wi-SUN FAN Stack	19 dBm	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.

Table 16. Power limits for WB-DSSS PHYs on 20 dBm PA

Phy	Tx Power	Additional Condition
WB-DSSS All Phys	15 dBm	Under all conditions

Table 17. Power limits for MIOTY PHYs on 20 dBm PA

Phy	Tx Power	Additional Condition
MIOTY	20 dBm	If you duty cycle with 60ms out of 100ms in TX
MIOTY	19 dBm	Without duty cycling

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.

Table 18. Power limits for all certified PHYs on 14 dBm PA

Phy/Stack	Tx Power
TI 15.4 Stack	12.5 dBm
TI Wi-SUN FAN Stack	12.5 dBm
WB-DSSS PHYs	12.5 dBm
MIOTY PHYs	12.5 dBm
