CC1314R10: Power Table

Seamus Pu

Part Number: CC1314R10

Hi Expert,

According to SmartRF Stdio 7 version 2.29.0 , I can find a default power table for cc1314R10 as below capture.

I'm confused why the hex parameters of the power settings are all equal to 0xfffe?

Further, if I need to set the output power below 0 dBm, I have a very limited power range available to me.

Basically there are only 5 power levels available to me [0, -5, -10, -15, -20].

Do we have a more detail power table for reference and is there a calculation formula for the Hex parameter that sets the gain?

Best Regard,

Seamus

    Hi Seamus,

    I just checked this on my end and I'm seeing the same, which is not correct - we do have a PA table for the CC1314R10 variants, so I will reply with the latest table in this thread whilst I follow this up. Please allow a day so I can confirm the correct PA table.

    It is not practical for TI to find a recommended value for every step between those listed as most customers do not use them, but the customer can find them themselves if they have that need. For finding additional PA table values, more detailed information on how PA table values are found is given in Section 10 of SWRA640 (CC13xx/CC26xx Hardware Configuration and PCB Design Considerations): https://www.ti.com/lit/swra640

    Regards,

    Here is the CC1314R10 PA table that should be there:

    TX Power Setting Display Text
    0xfffe:0x00013f 14
    0xfffe:0x00cd1f 12.5
    0xfffe:0x006f0f 12
    0xfffe:0x007555 11
    0xfffe:0x005850 10
    0xfffe:0x0081a0 9
    0xfffe:0x00749d 8
    0xfffe:0x005896 7
    0xfffe:0x00398e 6
    0xfffe:0x002f8b 5
    0xfffe:0x0059de 4
    0xfffe:0x0047d9 3
    0xfffe:0x0046d8 2
    0xfffe:0x001985 1
    0xfffe:0x002fd0 0
    0xfffe:0x0018c8 -5
    0xfffe:0x000ec4 -10
    0xfffe:0x0008c2 -15
    0xfffe:0x0008c1 -20

    You can also import the attached config file into SmartRF Studio in order to save having to manually enter it: /cfs-file/__key/communityserver-discussions-components-files/156/pasettings_5F00_LP_5F00_EM_5F00_CC1314R10_5F00_patablefix.zip

    There has been an update to provide 2 additional bits of PA table resolution for the CC13x4 devices which looks not to be fully implemented in v2.29.0; this will be corrected in the next release.

    Regards,

    Zack
