ADC12DJ3200EVM: GUI Values for LMX2582 Low Level Always Read 0xFFFF
Part Number:ADC12DJ3200EVM
When using the EVM GUI the register values for the LMX2582 do not all appear correct. For instance, when programming the EVM for 1500MSPS and JMODE0 the OUTA/B PD check boxes are always checked. Viewing Low Level register 46(0x2E) the PD bits are indeed 0 but are not broken out in the Field View section. If I look at 47(0x2F) the Field View shows the PD bits and indicate they are '1' but in the datasheet those are reserved bits set to '1'.
Also most of the time when a manual Read Register is issued, only for LMX2582, it returns all 1's and this is displayed in the LMX tab. I am exploring how the LMX gets programmed and these issues are making it difficult.
I am running windows 10 with a rev A EVM.
Thank you.

UCC28740: Suspect UVLO problem and get destructive testing
Part Number:UCC28740
Hello,
I'm currently debugging a prototype of the UCC28740 + UCC24636.
5V - 2,5A
After one obvious correction around transformer primary (wrong polarisation) I get an unstable 5V on output. And the circuit cannot bear any load.
It seems that the UCC28740 was working properly on few switch, achieved to get a 5V but suffers a default and switch OFF.
We can see VDD drop below UVLO 7V
I was starting to investigate further with 2 differential probes but I burn a 2nd PCB (Rcs resistors). (on First PCB Rls, Rcs and UCC28740 burnt)
I got a differential probe between primary GND and VDD and the second one between primary GND and DRV.
Could the probe on the DRV triggers the Mosfet and build a short circuit on Rcs resistors?
Could you make a sanity check of my schematic before I go further on my live testing attempts?
Thank you

PGA300: aep transdcuers
Part Number:PGA300
According to the data sheet he maximum current the PGA300 is able to deliver to the strain gauge sensor is 1.5mA.
This limit the minimum strain gauge output impadance to 800Ohm in case of power supply of 1.5V and 1700Ohm in case of power supply of 2.5V.
We normally use 500Ohm or 350Ohm strain gauges.
There is any trick I can adopt to use the PGA300?

TPS92075: 40W Led driver using TPS92075
Part Number:TPS92075
Dear Texas Semiconductor,
I have a request for a led driver of 40W supplied with 230Vac.
The leds are made by a string of 18 leds, each one with 3V of voltage forward. The led current is 0.7 - 0.8A. The led configuration is in series.
The circuit doesn't need to be isolated, but it needs a PF minimum of 95% and of a THD better than possible (the machine should be certificated).
Is a TPS92075 a good choice for my application? I though to use the buck configuration...
Using the TPS92075 design calculation it seems possible to achieve such power.... Am I right?

Linux/AM3358: MCASP DMA data drops
Part Number:AM3358
Tool/software: Linux
I am using DMA to service the MCASP and using a known sine wave input to validate the setup. I am getting discontinuities in the wave at random intervals which look like dropped data. When this occurs the MCASP gives no indication of an overrun or DMA error.
I saw the following post which describes similar behavior:
https://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/150666
The solution for the post above was fix something that was missed in the initialization sequence.
In my case I am clocking data into the MCASP while using the transmit clocks (ACLKXCTL ASYNC bit is cleared). The TRM section 22.3.12.2 indicates the receive registers should be set prior to the transmit registers. However it also indicates if an external clock is used it must be running prior to initialization. If the transmit section clocks the receive section should it be configured first? At what point in this sequence should RFIFOCTL and REVTCTL be configured?

AFE58JD28: Question about power supply sequencing
Part Number:AFE58JD28
I am in the process of designing the system power supply for a device that included the AFE58JD28. In the datasheet (under NDA) section 11.1, figure 122 the timing of the power supply initialization is shown. I do not clearly understand the relationships between t1, t2, and t3. None of these value are exactly defined, and t1 and t3 are shown as having the same end points.
- I am assuming t1 is the allowable rise time of DVDD_1P2.
- I am assuming t2 is the allowable rise time of all other supplies. (?)
- I am assuming t3 is the allowable delay between enabling supplies.
Questions:
- Is t2 only specifying the allowed rise time of the noted supplied, or is it trying to indicate maximum DVDD_1P2 valid to the other supplies being vaild?
- Under the note, is t3 < t1 correct? Based on text I was expecting this to read t3 > t1.
- Based on the text, is it adequate to assure DVDD_1P2 > AVDD_1P8 while DVDD_1P2 < 1.2V, or should AVDD_1P8 be 0V while DVDD_1P2 < 1.2V
- Are there any power supply sequencing requirement during power down?
Thanks, Chip Weller

LM5170EVM-BIDIR: Special 12v Application (Buck Mode Only)
Part Number:LM5170EVM-BIDIR
I have a low volume (test apparatus) project that the LM5170EVM-BIDIR will fit perfectly if I can configure it to do the following:
1) Self-start upon the application of primary (input) power.
2) Input voltage could range from 10v to 16v
3) Operate in the "Buck Mode" only
4) Allow the output voltage level to be controlled via an analog signal source (potentiometer or other voltage source)
5) The output voltage would be varied, set, and regulated and could vary from 95% to 60% of the input voltage (Again, Buck Mode Only)
6) Operate in the 2 phase mode with the option of the stacking to a 4 phase mode depending upon the power level needed for the application
7) ...
I have developed, designed, and fabricated this type of apparatus using another manufacturer's Buck/Boost converter EVM and found that unit to be far more complicated than is desirable. Especially regarding what mist be done for the startup sequence upon power up. I'm hopeful that the LM5170EVM-BIDIR will be much simpler in this regard and the scalability of this converter (through stacking) will offer some serious benefits also.
Many thanks for your time and consideration!

TPS54233: Doesn't start if Input is below 4V
Part Number:TPS54233
Hello,
I have made 3.3V power supply using a TPS54233, It works fine if Vin or BATT_LIION_OUT is above 4.3V.
But when VIN or BATT_LIION_OUT is below 4.3V, it stops working, whereas according to the datasheet the component should work with Vin as low as 3.5V.
I have trie dwith lower values on C6 and C7, but the result is the same.
Could you help me to solve this problem please ?
Thank you in advance.
R1 and R5 are not connected.

Hi Guys ,
It has been several days that I am struggling with the I2C on the Launchpad cc2650 with contiki .
I just want to communicate with a temperature sensor using I2C.
Is there some template code that I can use ? or I must use the ti drivers and write my own driver ?
Thank you .

TAS5755M: Best practice for input of I2S signals to TAS5755M
Part Number:TAS5755M
I have a PCB design (mine) that uses an Analog Devices SSM3582 with I2S input, the client wants me to replace this Amp with the TAS5755M so I bought the TAS5755M Evaluation PCB and have it running well from an analog input.
My PCB design has 2 sources of I2S data, a TI TLV320ADC ADC and a Cypress CYBT-343026 (Ex Broadcom WICED module), I use a 74LVC157APW to select/switch between one source or the other. The issue is that the Cypress module doesn't have a MCLK output and the TAS5755M seems to need one. The signals I have are as follows
| TLV320ADC | CYBT343026 | SSM3582 | TAS5755M | Notes |
| MCLK | MCLK | TheTLV320ADC has a 12MHz Xtal feeding into MCLK | ||
| BCLK | I2S_PCM_CLK | BCLK | SCLK | This is the main clock at approx 1.4 MHz |
| WCLK | I2S_WS_PCM | FSYNC | LRCLK | This is the L/R or Frame Clock which changes polarity every 16 bits of the BCLK |
| DOUT | I2S_PCM_OUT | SDATA | SDIN | Digital Audio Data |
I read the datasheet for the TAS5755M and it seemed to indicate that is could work with no MCLK input but when I remove the link for the MCLK signal from the Eval PCB setup, I get no sound. Can the TAS5755M run with no MCLK? I can see that I could give it the same 12 MHz MCLK that's feeding the TLV320ADC but then that clock would have no relationship to the data streaming from the Cypress module when that was selected as the I2S signal source.

CCS: Missing support for Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator in Linux CCS release
Tool/software: Code Composer Studio
I'm using CCS 7.2 with C5517 EVM board under Windows and there is no problem. But now I need to use CCS for Linux.
I try to make setup as it is described at:
but I found missing full support for - Spectrum Digital Debug probes and Boards when try to create new -> Target configuration file. There is no support for Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator in the Connection combo box. See screen shot:
During CCS v8.0 installation I have added check for Spectrum Digital support.
Is it known issue for CCS for Linux releases or I'm missing something during installation?

Hi,
I was trying to implement IC2BMI160 from Simplelink Sensor and Actuator Plugin, but I realized I need non-RTOS version. Is there non-RTOS version hidden somewhere, or could you present guide where I can extract information from those development files to create non-RTOS version? I am not familiar with RTOS systems, and don't have time to learn it in near future.

ADS42JB69EVM: Difference Between Datasheet and EVM Design
Hi,
So on the eval board the additional R-C-R is recommended on the datasheet. That Additional R-C-R is not on the Eval board . Only the C is present. This usually leads me to believe that during testing you did not find that R-C-R necessary or effective. Any comments or recommendations on that? My layout is in a small area so I could use the space.

Hi team,
We are interested in the SIMPLELINK-SDK-VOICE-DETECTION-PLUGIN for the CC2642R, however, I only see examples for the MSP432P401R. Do we have any examples for any of the BLE devices?
Do we have any data showing the number of phrases we can support, the load on the M4F during detection/recognition, and the memory requirements?

TCA6408A: Time needed to clear default 1's from output register
Part Number:TCA6408A
Greetings,
I have encountered an odd problem using the TCA6408A. From the datasheet I understand that at power up the device configures all IOs to be inputs. The output register has default value of all 1s (0xFF). What I want to do is configure the outputs to be all 0s (0x00) by writing the output register and I want all the IOs to be outputs (using the direction register). I have successfully implemented all of this EXCEPT, what I have found is that even if I write the output register first setting it to (0x00) and then write the direction register setting all the IOs to outputs - I am still getting a 100 us blip on all the IOs where they go HIGH. It seems as though the TCA6408A is ignoring the order in which it received the I2C writes and is going ahead to set the direction to output first AND THEN applying my 0x00 value to the output register.
I have been able to work around this by first writing 0x00 to the output register, then performing a "dummy" read of the input register (just to introduce some delay), and finally writing the direction register to configure all the IOs to output.
My questions: Why do I need to introduce this delay between writing the output register and writing the direction register to get the part to actually put my desired values out on the IO lines at the time of the direction switch? Is the delay of reading the input register guaranteed to be a sufficient amount of time to ensure that the output register is stable by the time I switch all the IOs to outputs?
