CC2640: SIG qualification

Lenio Cacula
Genius 16900 points

Part Number: CC2640
Other Parts Discussed in Thread: CC2650,

Why does SIG require tests of certain parameters to which the customer has no influence or control?

More specifically, some of the tests in the RF-PHY section, such as stable modulation indexes, seem to be completely out of the control of the user. 

Our wiki goes into great length to explain some of those procedures. One excerpt is of particular interest for my question:

The CC2650-7ID also has an RF-PHY Qualified Design Listing (QDL) This is to demonstrate the ability of the CC2640/CC2650 to achieve RF-PHY certification only and cannot be reused in a customer application. For the rest of the software solution BLE2.x_CC26xx can be referred to during the product listing process.

 

It is my understanding that we cannot pre-qualify the device, even though there is nothing the user can do to have influence on the results. That is the portion that I would like more clarification. Can the customer save on some of those tests based on the characteristics of the CC2640?

Thank you!

    Hi Lenio,

    Good question, although it may be best to direct questions about SIG test requirements to SIG directly.

    Regarding pre-qualification, this option is available if you purchase a pre-certified module that contains a RF-PHY component or subsystem QDID. It's not possible to pre-qualify the wireless MCU device for PHY purposes since the layout of the antenna impacts RF performance. Note that the SIG PHY tests are usually performed at the test lab along with the regulatory tests.

    The customer can substantially reduce testing by using our protocol stack QDID and self testing adopted profiles with the PTS dongle ($99). This, along with the test evidence and listing fees is all that is required for SIG listing purposes.

    Best wishes
