LMX9838: RED and EN 300 328 V2.1.1 compliance

Friedrich Marc

Part Number: LMX9838

Hi,

Does the LMX9838 comply with the new RED directive and the EN 300 328 v2.1.1 ? If not, when do you plan to publish a report ?

Many thanks

LMX9838 is not supported in the Sub-1 GHz proprietary and 15.4 star networks forum. I have move your post to relevant forum

Hello Friedrich,

As I understand, the conformity with RED 2014/53/EU (or RTTE) is required only for final design. Components themselves are not subject to RED (or RTTE) conformity assessment.

As for EN 300 328 v2.1.1, this standard is fairly recent, so it may be months before certifying labs are ready to test it. As for certifying the LMX9838, this is an older device, and we are currently considering whether to certify it for EN 300 328 v2.1.1. Please check back with me in July this year, and I will have a better idea what our plans are.

Hello James,

Do you have any news on the LMX9838 certification ?

Many thanks.

Unfortunately the latest testing has confirmed that the LMX9838 is not passing the latest CE certification. Our sales and distribution teams are being informed of this result and they should be able to offer you more information in the coming days.

Thank you, James.

Is there a direct replacement for the LMX9838 that is compliant with the applicable standards for CE certification, FCC, and Industry Canada?

Stephen

0 James Lockridge19 over 6 years ago in reply to Stephen Kucharczuk

TI__Genius 14485 points

Stephen,

We do not have a direct replacement. Another TI module you can consider is CC2564MODA. Otherwise, 3rd-party module manufacturers may have a good solution that fits your needs.

We are working to debug and fix the module so it passes the certifying tests. However, I cannot give you an estimated timeline for this effort right now.

0 Stephen Kucharczuk over 6 years ago in reply to James Lockridge19

Thanks, James.

Do you know which tests the LMX9838 failed? We are using the LMX9838 at a reduced power level (not maximum power output), so there is a possibility that we might pass EN 300 328 V2.1.1, unless the LMX9838 failed something like Receiver Blocking. Any information would help.

Regards,

Stephen

I downloaded the Declaration of Conformity for the CC2564MODA. It shows compliance with EN 300 328 V1.9.1 (R&TTE). Is there a more up-to-date DoC that shows compliance with EN 300 328 V2.1.1 (RED)?

Stephen,

Currently we are not meeting RX spurious emissions for CE and FCC. We are working to fix this, but I'm not sure on the timeline for when we will find a fix. However, we comply with RX spurious emissions for Japan.

As for the CC2564MODA, I think it is qualified for EN 300 328 v2.1.1. If you create a new post for the part with that question, the system will notify the applications engineer who supports that device.

Hi James,

Do you have an idea when the LMX9838 will be fixed to be compliant with the RED Directive? We are currently using this module on a medical device and changing to another module would mean a lot of paperwork & new testings.

Hi Anne,

The module now passes the EN 300 328 2.1.1 test. All the RF testing is completed and passes. Our next step is to do EMC testing and create the declaration of conformity. We expect to complete this in the next 2-4 weeks.

Hi James,

Were any changes made to the module to allow it to pass EN 300 328 2.1.1? We have inventory of parts and will need to know the compliance status of these.

Thanks,
Glen

0 James Lockridge19 over 6 years ago in reply to Glen Robinson

TI__Genius 14485 points

We did not make any changes to the module. We thoroughly reviewed our test procedure with the test house to ensure we sent the correct commands to the module in testing.

We are currently testing for EN 301 498-17 now. Once testing is completed, the units you have in inventory should be fully compliant.

0 Glen Robinson over 6 years ago in reply to James Lockridge19

Hi James,

That's good news. Should we expect production to be back online soon after testing is completed? We put in an order several weeks ago through our distributor and it was rejected by the factory. Am I correct in assuming that compliance testing is the reason that the order was not fulfilled?

Thanks,
Glen

0 James Lockridge19 over 6 years ago in reply to Glen Robinson

TI__Genius 14485 points

Yes, we put shipping on hold for compliance testing. We'll resume production once testing is completed.

Testing is complete and the LMX9838 passes EN 300 328 2.1.1.

We are currently preparing the declaration of conformity now that we have the test reports.

Hello Anne,

Here is the response I received from my product line manager today:

"Texas Instruments has decided to obsolete production for the LMX9838 BT Module and move it to End of Life. As such it is no longer recommended for new designs. Official notification to all existing customers will be provided shortly."

Hi, Glen.

We have not been able to find information regarding the status of this part through other channels, and we have not been able to make a last time buy. So we modified our circuit board to use the SPBT3.0DP2 Bluetooth module instead of the LMX9838. Last week we passed all EMC testing with the SPBT3.0DP2 Bluetooth module.

Glen,

I am still told that TI will send a formal communication shortly. Unfortunately, I don't have a timeframe for when you will receive it.

For anyone looking to replace the LMX9838 module in their system, AmpedRF builds a certified module with the CC2564. The part number is BT53.

Hi James,

We were told on Sep 18 that "Official notification to all existing customers will be provided shortly.". For me, and I suspect many others here, two months is not "shortly". We have already selected a new BT module and are updating our designs, but this affects multiple products and will be a significant undertaking for us. We are trying to figure out ASAP whether we will be able to get more parts in the short-term to help us get through the transition. We cannot wait another two months for an answer.

Could you please provide an explanation of what is going on here? This part has been in limbo since June and we have not yet had a satisfactory response from TI.

Thanks,

Glen

Regarding LMX9838 radio certifications according to EN300328 it is tested for the extreme temperatures of 0 deg C and +40 deg C although the data sheet state that the module
operational temperature range is -40 to +85 deg C. What is the reason for the limited temperature range?

(The reason for asking is that our end product is specified to +50 deg C and unfortunately we cannot refer to your test reports.)

Let me know,

Michael

0 James Lockridge19 over 6 years ago in reply to Michael O'Hearn

TI__Genius 14485 points

Hi Michael,

In the EN 300 328 v1.8.1 report in 2014, those temperatures (0 C and 40 C) were tested and data was provided in the report. I'm not sure why they chose to test a temperature range that is different from the range in the datasheet. The subsequent reports for v1.9.1 and v2.1.1 were spot checks based on that report, so the device was only tested at room temperature, 25 C, for the more recent reports.

0 Michael O'Hearn over 6 years ago in reply to James Lockridge19

Intellectual 270 points

Is there a test report for EN300328 v1.7.1 for LMX9838?

We have received newer reports (for v1.8.1, v1.9.1 and v2.1.1) earlier.

Thanks in advance.

Hi, James.

As Glen has pointed out previously, we were told on September 18 that "Official notification to all existing customers will be provided shortly." Our company is transitioning to a replacement Bluetooth module, but during that time we need to fill sales orders with the version of our product that uses the LMX9838. Our printed circuit board manufacturer has been able to find LMX9838 chips from a broker, but 100% of the chips are failing due to internal damage.

This is now an urgent matter. Can TI please provide customers with a Last Time Buy of LMX9838 chips?

Thanks,

Stephen
