This issue happens when master send the address to F280039 to request a read. The address has matched the one in the F280039 so the F280039 should send a ACK to inform the master, Below is the waveform: For better illustration, here's the same picture without any marking Our theory is the RTA is mis-triggered. Since TCA9511 already states the risk of RTA mis-triggering, when the Vol is too high (in this case, the low level onput of TCA9511 is 0.68V), customer should consider lowering the Vol. However, The TCA9511 is on the end-user board, not the customer board, so they can only suggest the end user to decrease the Vol. Before they gives the suggestion, they want to comfirm that if this is the result of RTA, and if droping the Vol to 0.6 (or other recommend threshold) can solve the issue. Could you please comfiming the below item? Is this a behaviour of RTA casuing the false rising edge? If the end-user decrease the Vol to below 0.6V (or other recommend threshold), can it make sure that the RTA won't be triggered?

Following reports from end customers, we have noticed issues with the consistency of the data provided by the PGA970. In general, we use this component to read LVDT sensors without any further processing. Therefore, the ARM is turned off, and data transfer occurs only via SPI (configured at approximately 900 kHz). Our analysis revealed that the demodulation registers (32 bits wide) read via SPI are corrupted by the PGA970 itself. Specifically, reading the entire register requires two 16-bit SPI requests. Apparently, the PGA lacks a mechanism to prevent these registers from being updated during the read operation. Therefore, when reading a 32-bit register, the first 16 bits (MSB) belong to the first sample, while the second 16 bits belong to the next sample. This issue is most evident when the value straddles the 16-bit boundary (as a raw numerical position). For example (for a generic demodulation register), given two consecutive samples as follows: 0x0000 FFEA 0x0001 0023 sometimes the SPI read result is: 0x0001 FFEA or 0x0000 0023 As seen in the example, the two acquisitions made by the PGA970 may, at the SPI transfer level, be mixed in certain cases, corrupting the final data. Since these issues were identified in a safety-critical project (under DO-178C), I need to provide definitive documentation to submit to the certifying authority (EASA). Is it possible to obtain an “errata” document or an official document confirming this behavior (with a tracking number)? Thanks in advance.

Thanks for assisting me. 2.7V battery is for backup? -Yes. This is a backup system and the 2.7V is a battery for backup . is the 12V system from 12V car battery -No. The 12V system is not a car battery. It can be assumed that the 12V is a very stable power source with minimal voltage ripple. does this device need to startup with 2.7Vin with Vout=0V -Not really. Since this is a backup system. The 2.7V Vin will only be selected by the power MUX if the 12V power fails This info might be useful. I am using a TPS2121 power MUX. The 12V power will either be 0V(when fail) or 12V(when normal). The MUX will switchover to the battery when 12V fails. It can be assumed that the DCDC at the output never sees 2.7V as that is the battery's voltage when the capacity is low. The battery will mostly be fully charged in an event that the12V rail fails. I am also considering putting the DCDC at the input path instead of the output. That way I can toggle EN to only ON the DCDC whenever 12V rail fails. This is to prevent the DCDC unnecessary power loss when the battery path is not needed. Maybe I should be using the TPS61088 instead if I am opting for this concept. Can you recommend me any boost converters for 3V to 12V @ 500mA too, please?

I am honestly not sure whether this would work, since DMM expects one of the two stacks to be the BLE-Stack. There may be some configurations in DMM that are not possible to adjust. Can you do a comparison of the TI 15.4.Stack DMM example (sensor.c etc) and the BLE DMM example (simple_peripheral.c etc) and see how they initialize DMMPolicy/DMMSch?

Did a storm occur? I hope everything is well with you! Regarding this table, it is perfect. I would like to ask what this average voltage means? Did you test it using the voltage divider method with two resistors? If so, what is the pull-up voltage? i guess it's 5V? So does the average voltage mean the voltage of the temperature sensing resistor to ground?

The eval board is operated on a +5V supply, which is connected to Vin1. 10 MHz OCXO(+2dBm) is given at PRIREF_P and 48 MHZ OCXO (0dBm) is given at XO_P connectors on the eval board respectively. The OUT0_P and OUT7_P are enabled to give 100 MHz. When the reference input switching mode is set as Auto Non-Revertive, we get a 100MHz output with a clean phase noise with no spikes in the phase noise plot. The image is attached below. Whereas, when we set the switching mode to manual holdover, we observe spikes in the phase noise of 100 MHz. The image is also attached below. The eval board is being programmed using TICSPro GUI. The programming files of both cases are attached below. 100 MHz auto non revertive.txt 100 MHz manual holdover.txt We want to get a clean phase noise in the manual holdover mode as well. Any insights into this issue would be greatly helpful. Regards, Suchitra Ramamoorthy.LMK05318BEVMLMK05318B
