CC1125: CC1125

Hi Rob,

Have you looked at the CC1101 for your application? 

The CC1101 supports 300-348 MHz and 387-464 MHz, along with Manchester encoding - Section 16 of the CC1101 Datasheet: https://www.ti.com/lit/swrs061 discusses the possible modulation formats so you can check if it is suitable for your design.

Sadly it still has a hole in the spectrum where i need to operate.

Looking through our product range, the CC13x0 and CC13x2 devices do cover this frequency range (just):

• CC1310 Datasheet: https://www.ti.com/lit/swrs181 - Section 5.5 
• CC1311R3 Datasheet: https://www.ti.com/lit/swrs256 - Section 8.9

• CC1312R Datasheet: https://www.ti.com/lit/swrs210 - Section 8.9

However, there has been limited testing for this frequency band and you may have to both adjust the PHY settings and tune the output matching network of the reference design if the performance isn't what you need it to be.

For more information:

There is more limited support for Manchester encoding on the CC13xx devices so I would advise checking the device/SDK documentation. Within the relevant SDK documentation on https://dev.ti.com/tirex (the CC13x0 devices have a separate SDK to the other devices), go to Documents -> Proprietary RF -> Proprietary RF User's Guide and search for Manchester encoding:

Other documentation to check is:

• SWCU185 (CC13x2, CC26x2 SimpleLink Wireless MCU Technical Reference Manual): https://www.ti.com/lit/swcu185
