CC1310: frequency bands and errata sheet

Chris sakowski

Part Number: CC1310

The document titled "CC1310 SimpleLink™ Wireless MCU Silicon Errata" states that there are current limitations to the frequency bands, modulation types and data rates of the CC1310.  Have these u[dates been rolled into any of the CC1310 production parts yet?  We are considering this part for a new design.  The 100kbps data rate should be ok for us.  The 4-FSK is not necessarily needed yet.  

Is there any transmit frequency coverage between 876MHz and 902MHz?  Is there any transmit frequency coverage above 928?  Is there any Transmit frequency coverage in the 359MHz-527MHz range, per the data sheet?

Thank you!

    The Errata is not fully updated. Data rates of 200, 300, 400 and 500 kbps 2-GFSK have been fully characterized. Register settings are provided by the SmartRF Studio SW tool. 100 kbps is no problem and we can help with settings if you decide to use this data rate.

    The chip covers 861 - 1054 MHz operation. 359 - 439 MHz operation is also covered. We have fully characterized the PLL/VCO for 359 - 439 MHz frequency band, but we have notdone a full RF characterization nor do we have a reference design. That said, using the 433 MHz reference design should be ok for 359 - 439 MHz operation and the performance will be similar to 433 MHz operation

    Thank you for the quick reply! Can you comment on whether or not any frequencies in the 439-527MHz range are currently (or could be) supported? Is the limitation for covering those frequencies in the reference design, or in the chip itself?

    Thank you again!

    Frequencies in the 431-527 MHz range are supported. Same as previous post, the PLL/VCO has been characterized for this frequency band, but we have not done a full RF characterization nor do we have a reference design. The supported frequency bands are given by the fully on-chip VCO, which has a finite frequency range. The VCO frequency is divided by 5, 6, 10, 12, 15 to give the frequency bands listed in the data sheet. Example: 861 - 1054 MHz uses DIV = 5 and 431 - 527 MHz uses DIV = 10.
