However, you can choose to have additional (4) IWRL6432WMOD to have overlap and better/longer Field of View range. The mmWave radar has in-built algorithm to reject any interference/cross talk from any other mmWave radar.

When I extracted the folder, the correct file (such as .lib, .sub, or .cir) for the spice model has not been found. Could you please guide me where to find it. or I would really appreciate if you could provide the correct spice model file so that I could run the simulation. The file I downloaded is ticked in Red Marker as seen in the screenshoot attached. please kindly review it for your reference.

I don't expect significant differences in performance with older revisions, but let me look into sending you a new board. Could you please provide a preferred name, shipping address, and email? You can also directly message me if you prefer not to post this information publicly. Please also send back the board you are currently using for TI to review. Thanks! Miranahttps://e2e.ti.com/support/rf-microwave-group/rf-microwave/f/rf-microwave-forum/1653409/afe7920evm-serdes-fifo-error/6380073Thu, 11 Jun 2026 21:38:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:aa6525f7-e28b-4fe1-8a03-47664ee418cfAman ThombreHi Taro, Please try the modifications I suggested via email. As we had to upgrade to JESD204C and use a new lane rate, we will likely have to make a few more modifications to the 204C IP. Thanks! Amanhttps://e2e.ti.com/support/rf-microwave-group/rf-microwave/f/rf-microwave-forum/1649125/afe7920evm-request-for-technical-review-regarding-potential-defect-in-afe7920evm/6379164Thu, 11 Jun 2026 10:54:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:fa674ecd-49fb-4443-bb9f-9f256812f50eMinho ChoiHi Mirana, I would appreciate a prompt response to my previous email. I would like to determine as soon as possible whether this issue is caused by a hardware defect. If the board is indeed defective, please let me know whether a replacement or refund can be provided. I would also like to reiterate a point that continues to concern me. I suspect that the board originally shipped to us may have been an older revision ending with "C". As I have mentioned several times before, when I perform exactly the same setup and sequence of operations, the board with a revision ending in "D" (a board borrowed from another company, marked "AFE7920EVM DC101D" above the serial number label) works correctly without any issues. However, the board that I purchased, which is the revision ending in "C", consistently exhibits the problems described earlier and does not function properly. Attached below is a photo of the packaging box of the board that I purchased. The SEAL DT on the label shows "08/10/20" , which suggests that the unit may have been manufactured or packaged quite a long time ago. Therefore, I am also wondering whether the issue could be related to being supplied with an older board revision that is incompatible with the setup we are trying to use. I would appreciate it if you could investigate this possibility as well and provide clarification. Thank you for your support.

I'll share this E2E post with our customer so he can reply when needed. We are currently using the afe7950, and 4GHz 200MHz OFDM communication signals are functioning well for both transmission and reception. In another project, we are using a 4GHz carrier frequency raised to 4.87GHz. Since we suspect errors caused by IQ imbalance when raising the frequency to 4.87GHz, we intend to apply both the QMC automatic and manual correction functions. I am sending this email to request technical support regarding this issue. We have consulted various manuals and attempted different approaches, but we have not been able to find a solution regarding the configuration. Currently, when demodulating the IQ using a Spectrum IQ Analyzer, the IQ waveform exhibits vertical mirroring, in-phase, and Q-axis disappearance at regular intervals.

The run sequence was: setup.py devinit.py AFE_softReset_debug.py The debug script calls AFE.softReset() only. During AFE.softReset(), Latte printed: #====== #Executing .. AFE79xx/bringup/AFE_softReset_debug.py #Start Time 2026-06-09 15:43:44.028000 DONOT_OPEN_Atharv_FULL - Device registers reset. SPI is not working. #Error: exceptions must be old-style classes or derived from BaseException, not NoneType From the log, the script did enter AFE.softReset(), and the device register reset step was executed. However, the AFE SPI readback check failed during softReset. At this point, it looks like the AFE SPI interface is not being enabled or is not responding correctly. I also checked the soldering condition of the SPI lines with a multimeter, and confirmed that the connections appear to be continuous and properly connected. I have also attached the related screenshots and the Python file used to run AFE.softReset().

C functions can be run from latte using format: CAPI. doRxDsaCalib(0,15,0,0,0) #Runs doRxDsaCalib function for all channels. When rxChainForCalib is set to 0xF, I see the output packet has 1327 entries and calibration fails with an error even if one out of the 4 channels input is not connected. When any individual channel calibration is run, the output packet has 370 entries and errors out if that particular channel input is not connected. Can you please check if rxChainForCalib parameter is getting passed correctly to the function?

However, when attempting to adjust to an IQ rate of 983.04 MHz, a Serdes-FIFO error is consistently reported. I believe the issue lies in the configuration of the 204C IP core downloaded from TI. Attached are the header file configuration of the 204C IP and the transceiver configuration in Latte. What modifications are needed? Additionally, is there any reference design for the ZCU102 at an IQ rate of 983.04 MHz?
