CC1101: CC1101

Part Number: CC1101
Other Parts Discussed in Thread: SMARTRFTRXEBK

Sir, We are developing Wireless Communication devices which requires CC1101 RF transciever for data transmission. I have some doubts regarding CC1101 IC. In Datasheet, Operating bands are given as 315 MHz,433 MHz, 868 MHz, 915 MHz and mentioned it will operate in US and Europe. Since I am from India and I want to know whether it will operate/work in India and Globally.

    Quick comment, this community is monitored by both female and male TI engineers......

    CC1101 will work in India and globally. We have numerous customers using this part in India.

    The front page of the data sheet gives the operating bands as 315 MHz,433 MHz, 868 MHz, 915 MHz. This is just short for the most commonly used frequency bands. As an example, the frequency band in US is 902-928, but is commonly referred to as 915 MHz band. In Europe there is a frequency band 863-870 MHz, but this is commonly referred to as 868 MHz. What you should do is to look at page 8 in the CC1101 data sheet which gives the frequency range as 300-348 MHz, 387-464 MHz, and 779-928 MHz.

    Sverre,

             Thanks. But I want to know whether this band (433 MHz) or any other RF transceiver band (315 MHz,868 MHz,915 HHz) will work in all countries? We are developing a global product and it should work in all countries. If none of these band works globally, then help us what kind of transceiver will be suitable for our requirement.

    Thanks,

    A.Uvaise Mohamed

    433 MHz is a global frequency. Please note though that the regulatory requirements are different for different parts of the world. The output power in US for instance is limited to less than 0 dBm at this frequency. In Europe you can transmit up to +10 dBm.

    868 MHz is used in Europe and 915 MHz is used in the US, but the same RF design can be used for both frequency bands (that's why the reference design is named 868/915 MHz). Australia, Canada, South America and the Far East also use either 868 MHz or 915 MHz. Again, regulatory requirements are different for different parts of the world.

    Hi Sverre,

               What is the difference between these two Development kits (CC1101DK433 and SmartRFTrxEBK) ?

               I am opted to use CC1101 IC in our product. So, I need to ensure all the Functions are working Properly.

               And TER from TEXAS suggested me to use SmartRFTrxEBK  Development kit for evaluation. So, Please give a difference between above two dev kits?

    Thanks,

    A.Uvaise

    CC1101DK433 consists of two boards; CC1101EM-433 and SmartRF04EB.

    EM: A small module containing CC1101 and the needed external components (crystal, supply decoupling, balun, filtering)
    EB: A motherboard which contains various user interface circuitry, a USB MCU, and a USB interface that can be connected to a PC.

    SmartRFTrxEB is a motherboard similar to SmartRF04EB and supports CC1101. SmartRFTrxEBK does not include any EM. If you are looking for a CC1101 development kit you should order CC1101DK433.

    Thank you Sverre. Do this Kit have any Header connector support that could perform SPI wired interface with another Master controller Development kit?

    The answer is "yes", you can interface another MCU devlopment kit through SPI and GDO lines available on I/O connectors

    See section 6.6: www.ti.com/.../swru040c.pdf

    Sverre,

    1. I spoke with TER regarding this CC1101 Dev kit and she suggested use the devkit that I mentioned in the link below.
    www.ti.com/lit/ug/swru294a/swru294a.pdf
    2. Can u please describe about the difference between the two dev kits?
    3. And what I had asked in my previous query is " Do this dev kit have any wire/pin that could connect with CC1101 Devkit and third party sensor kit?

    Thanks,
    Uvaise

    TrxEB is simply a newer generation development board compared to SmartRF04EB, which comes with the CC1101DK433.

    You can connect to external MCU and sensor kit through I/O connectors on the TrxEB (and SmartRF04EB).

    1. Means TrxEB have all the expansion boards and Modules in its Kit whatever available in the CC1101DK433 kit. Right?

    2. I have attached an image file. Please check it Whether the kit have such cables to interface with TI kit and Third party kit?

    Thanks,

    Uvaise

    Please refer to the user guides for the I/O connectors. There are pictures of the boards and you find the information you need in there.

    I couldn't find anything like that. That's why I asked to you. Though this is your product, Why are you answering like this? Please answer directly about the availability of cable. :-/

    The user guides I referred to shows the different I/O connectors and which signals are available. There are no cables with the kit except for a USB cable.
