Part Number:AM3352
Tool/software: TI-RTOS
Hi Champs,
We would like to insert Bus switch (SN74CBT3244C) between SD card and AM3352 (MMC/SD out put pins) .
This bus switch purpose is to prevent reverse current to AM335x side when Device power is shout down unexpectedly.
We are trying to consider "delay" on the Bus switch.
However, if between MMC0_CLK and MMC_CMD/DAT occur "delay", Can we control this delay on the AM3352 ?
If so, could you please tell us this resolution.
Regards,

Part Number:SN65LVDS104
Hi，all
There is no integrated 100ohm termination resistor between A and B inputs of SN65LVDS104.
(1)The 100-Ω externalIs between A and B is necessary?
(2)If there is no 100-Ω external resistor between A and B，Can the chip work properly in long-term？
Regards,
Guo
Part Number:MUX36S16
Hello,
i just wanted to ask if the MUX36S16 Multiplexer meets the AEC-Q standard?
has the MUX36S16 been already failed the AEC-Q Standard test or if the MUX36S16 hasn't been tested at all?
if it hasn't been tested at all, then it would be very helpful to know why the MUX36S16 doesn't meet the AEC-Q Standard?
Thanks in advance

Part Number:SRC4382
Hello.
I have a simple question, I hope.
In the SRC4382, how is the output sample rate from the sample-rate-converter determined?
On p.33 of the datasheet, this signal is shown as INT_SYNC, but it is not mentioned elsewhere how this signal is generated. Does it simply pick it up from the frame clock of one of the sources selected to take the SRC output?
Many thanks in advance for your help.
Part Number:LM94023
Hello,
I would like to know that how to calculate the output impedance of LM94023. The reason is my customer want to know this parameter and this parameter unfortunately doesn't on datasheet.
I guess I'm able to calculate by the graph of Load regulation. Is this understanding is correct?
Best regards,

I have faced some problem while trying to debug my launchpad. I tried to add breakpoints for the buttons however it does not seem to be working.
Please advice on what I can do.
I am using SIMPLELINK_CC26X2_SDK_2.30.00.34
and my ccs version is 8.3.0.00009
Thank you
Part Number:ISO7741
Hello support team,
Is there EMI test data of ISO77xx series ?
(For example, a graph which indicates that ISO77xx clears CISPR22)
And regarding the countermeasures for EMI, is there a constraint on the board pattern? Or do you have any recommended patterns?
Our customer would like to make it a reference.
Sincerely,
M. Tachibana
Part Number:TPS61193
Hi
I am using the TPS61193 to drive the backlight of a LCD display. The backlight is flickering during startup as can be seen on the screenshots of output voltage of the TPS61193 to the LEDs (see image)
Sometimes it takes several seconds to stabilize the LED voltage sometimes it just works without flickering.
I run with 5V input, 800khz switching, 35mA current limit. The LCD backlight diode string contains a zener diode (rating not specified in datasheet), could this cause some trouble with the TPS61193 ?
Is it normal behaviour that it takes several seconds for the output voltage to ramp up ?
Part Number:SN74LVTH125
Hi Team,
What's the max Tj and thermal impedance information of SN74LVTH125DR? thank you.
Part Number:ADS1261EVM
Hi,
I purchased ADS1261EVM to test some application. I have installed Delta-Sigma ADC EvaluaTIon Software software and drivers and when I started software I saw that board is connected but the register map on startup screen was not visible. I tried several things but the register map was still not visible. Then I started to play with buttons and of course, I put it to firmware update mode so now I can't do anything. I noticed a post on this forum that has a description of how to solve that. I followed those steps but when I got to a part where I had to locate FIRMWARE_UPDATE.bat this file was not at a specified location.
I would like to ask if this file can be posted somehow so we can download it, or if it can be added to installation package again? Then I would like to ask if there is some specific procedure to be able to see a register map when a device is connected or this should be automatically detected.
Thank you very much for your help

Part Number:TM4C129XNCZAD
Hello there,
Our engineers tried very hard to communicate a TM4C129XNCZAD with a Fujitsu FRAM, MB85RS512TPNF-G-JNERE1 through an SPI bus using the TI APIs. Unfortunately, they failed. Then, they used the same I/Os as GPIOs and generated the SPI timing using their own code. The code worked beautifully but too slow. They reckon that the problem might be caused by the are changing SPI CS line generated by the APIs in the middle of one 32-bit transfer. Does anyone know anything similar and the solution? Many thanks.
Part Number:TPS8268180
Hi Experts,
Can you help to share with us for the TPS8268180 RoHS report and material content report? We can not find it on ti.com, and what we can find is only attached file but doesn't include such info.

Thanks.
Part Number:IWR6843ISK
Tool/software: Code Composer Studio
Hi,
I have recently purchased a IWR6843ISK and MMWAVEICBOOST to work on ranging projects. to get started, I started to read several user guides and data sheet. I also watched the training videos from link [1]. In particular, I wanted to build/simulate project the same way explained in the videos series in link [2], however I am getting error in building the project. I also tried the mmwave_sdk demo from TI resource explorer demos however still failing to build the project. Please see the error code in the following.
P.S. I have installed code composer studio v8 and mmwave_sdk 3.01.01.02.
At this stage, I am trying to make the tools work and be able to test the demo project so I can move on development the software/algorithm for our application/product. I would appreciate it if you could advise me how to proceed next.

Part Number:LM317A
Hi Team,
Q1. The datasheet mentions about the External Capacitance at section 8.4.1, the customer can not use tantalum and
and aluminum electrolytic capacitor. It is also written that LM317A is not necessary output capacitors.
If the customer wants to add the ceramic capacitors at output, how many capacity values is better?
Condition :
Vin : 24V
Vout : 15V
Iout : 500mA (Max)
Q2 : The bypass capacitor
Is the bypass capacitor (C2) at Figure 17 recommended? Because the TLV317A's EVM has the same circuit. In case of the above condition, the C2 is mandatory?
Regards,
Ogasawara
