Original question:

CC1020: Sensitivity issue in CC1020 Transceiver

CC1020: Smart RF studio 6 version installation issue

Surya Ganesh

Part Number: CC1020

Tool/software:

Hi,

I'm experiencing an issue while trying to install SmartRF Studio 6 to configure the CC1020 transceiver chipset. After installation, I encountered an error popup. I’ve attached an image for your reference.

I attempted the installation on a Windows 11 Pro system. Could you please assist in resolving this issue?

Thank you.

Thanks,

Surya

    Hi Surya,

    The problem is that these old evaluation boards are using a parallel port as interface and the drivers (tvicport.sys) are no longer supported.

    See these older E2E case for further details: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/1371122/cc1020-smartrf-studio-installation-problems-for-cc1020-transceivers?tisearch=e2e-sitesearch&keymatch=cc1020#

    Is there any alternate part for the CC1020 RF transceiver. It would be great if the replacement has the same footprint and pin compatibility and also supports the latest version of SmartRF Studio. If any such device is available, please suggest.

    Hi Surya,

    This will depend on the radio protocol that you want to use. Do you need to be compatible with an older product, or is this a completely new development?

    Hi Surya,

    Which frequency, radio PHY are you targeting? Are you using any special feature? Do you have any more details that you are willing to share?

    Regards,

    We initially built several boards using the CC1020 RF transceiver. However, we’re currently facing a sensitivity issue. According to the datasheet, the expected sensitivity is around –112 dBm with 25 kHz channel spacing and a 4.8 kbps baud rate, but in our testing, we’re only achieving around –98 dBm.

    To troubleshoot this, we tried configuring the CC1020 using SmartRF Studio 6, but encountered driver issues that prevented proper setup. We’re looking for alternative ways to verify the sensitivity performance of the CC1020. Additionally, if there is any alternate part that matches the CC1020 in terms of footprint and pin compatibility, and also supports the latest version of SmartRF Studio, please suggest.  Below are the specifications of transmitter and receiver.

    Hi Surya,

    I've tried to find a workaround here but there is unfortunately not a more recent device that is pin-to-pin compatible with the CC1020.

    If the information linked by Øyvind does not resolve this, we cannot recommend another action for getting it to communicate with SmartRF Studio other than migrating to a more recent device.

    Is the TX performance as expected?

    Are you using any external LNA/FEM or the the CC1020 standalone?

    Regards,

    Zack
