Our customer encountered a problem. In the ti wliink8 single-antenna solution, the car was connected to the iphone, and the connection abnormality was relatively high. Bluetooth reported ̈linklost ̈, causing Bluetooth communication to be abnormal.(Please visit the site to view this file)
Part Number:TPS3808
Hi Team,
The datasheet shows the following about RESET delay time.
Does the value include CT capacitor tolerance?
If so, could you tell me CT capacitor tolerance about CT=100pF and CT=180nF?
Best Regards,
Yaita
Part Number:MSP430-GCC-OPENSOURCE
The latest 6_1_0_0 MSP430-GCC-OPENSOURCE GCC announcement has no link to msp430-gcc-support-files.
"software-dl.ti.com/.../index_FDS.html"
And the last released headers msp430-gcc-support-files-1.205.zip isn't accessible from the following URL.
"software-dl.ti.com/.../msp430-gcc-support-files-1.205.zip"
Where can I get the latest msp430 gcc support files?
Part Number:UC3842
I have built a non-isolated boost converter which should operate with 1-phase rectified DC as well as three phase rectified DC. I have validated the converter for three phase rectified DC and now I am trying to operate converter with 1-phase rectified DC, but when I am applying 1-phase rectified DC IGBT is getting damaged immediately. Is UC3842b compatible with 1-phase rectified DC (without filter capacitor)?
Part Number:TPS65988
I got a PD FW from vendor however the GPIO0 is not driving high for expectation, the pin is only connected to Intel TBT RESET# for reset purpose. When I create a new project by myself the issue disappears, There are many settings different between my and vendors, but I am not sure what is the root cause? Are there any HW portions need to be noticed? Or it is a just FW settings issue?
Part Number:TPS5405
Hi Team
We design a DC/DC module using TPS5405 and find output voltage drop down when the load current increase. we try to change frequency, inductor, and Comp, but there are on improvement.
we also use a wire to connect GND Pin and anode of D11. it is the same result. Would you please give some advise ?

Part Number:TLV1805-Q1
Hello,
Would you please explain how the D4 Schottky between IN+ and IN- works? And in what situation? In the datasheet this is for an event like reverse supply, but I cannot understand what is the concern.
I would also like you to explain how the D6 Zener across the load works. I cannot understand how floating load can turn on the FET.
Thanks.

Part Number:ADS42JB69EVM
Hi,
If we buy ADS42JB69EVM, is TSW14J56EVM included?
Or do we need to buy TSW14J56EVM in addition to ADS42JB69EVM?

Part Number:TPS2378
Dear Specialists,
My customer is considering POE input circuit and has a question.
I would be grateful if you could advise?
---
I'm thinking about voltage rating of Bob Smith Terminination capacitor.
http://www.tij.co.jp/jp/lit/ug/slvu682/slvu682.pdf
According to this document, voltage rating of C5 - C8 is 100V.
I'd like to change to 50V from 100V.
When PoE power is supplied, a maximum of 57 V is applied as the voltage between TP 2 and TP 3.
Since the voltage is divided by the transformer, a voltage of 28.5 V is applied between C5 and C6.
is it correct ?
If so, I think there is no problem with 50V.

I appreciate your breat help.

I didn't see the "am57xx-evm.dts" for the present SDK 5_1. Could you help me to find the exact device tree for am5728-evm board?
Part Number:LMV7219
Dear Sir
We got samples of 2 pcs from difference reel with same date code.
After checked mold compound of these 2 smaples is difference as pictures .
Do you have reason why these 2 samples have difference mold compound ?
Also marking texture seem difference .
Part Number:TM4C1294KCPDT
Tool/software: Code Composer Studio
Hi Everyone,
I am developing an embedded application on TM4C1294NCPDT using TI-RTOS V2.16. Compiler CCS v6.2.
I want to change the Build output directory from default "${BuildDirectory}/Debug" to my custom Build output path. Can you help me how to change that.
Regards,
Prem.
Part Number:CC1200
Hello,
My customers are trying to change the parameter of TOC_CFG.TOC_LIMIT from 00 to 01.
To change the parameter, do they need to set the additional parameter?
Especially, we want to know the default settings of TOC_CFG.TOC_PRE_SYNC_BLOCKLEN and TOC_CFG.TOC_POST_SYNC_BLOCKLEN in case of changing TOC_CFG.TOC_LIMIT to 01.
And is there any bad influence by changing the parameter?
They are using CC1200 as a receiver.
Because the transmitter's reference clock source is a RC oscillator, the variation of frequency is very large.
As a result, in case TOC_CFG.TOC_LIMIT is 00, the receiver (CC1200) cannot receive the many packets.

Nomo
Part Number:CC1200
Hello,
Please let me confirm the following question.
All of these questions are related to 6.6 Bit Synchronization in user's guide.
1.What is the target of "Symbol Rate Offset Tolerance" in Table 19, a receiver side or a transmitter side?
Also, does the table show the condition to complete the bit synchronization?
2.What is "Required Preamble Length"?
Is this the preamble length to complete the bit synchronization in the receiver side?
3.What does mean "0.5 byte (only for gain adjustment)"?
Is only 0.5 byte needed to complete the bit synchronization and is there any additional re-synchronization?
Best Regards,
Nomo

Hello,
Could you tell me the detail meaning of the parameter of the TOC_CFG register?
We want to understand what "Proportional scale factor" and "Integral scale factor" are.

Part Number:DP83822IF
Hi all
Would you mind if we ask DP83822IF?
<Question1>
On the datasheet Electrical Characteristics, there is PMD OUTPUTS VOD MDI 100BASE-TX.
We would like to confirm test condtion of PMD OUTPUTS VOD MDI 100BASE-TX.
We assume followings;
-100 termination across differential output, measured differentially after 1:1 transformer
Is our recognition correct?
<Question2>
If you have compliance test result with DP83822EVM, could you share us it as reference data?
Kind regards,
Hirotaka Matsumoto
Part Number:PCM3070
Hi Team
We use PCM9211+PCM3070+TAS5548+TAS5631B to develop one active speaker. We have one issue need to be solved.
When we set the Bass shelf gain from -3 to 3, the SPL vs FREQ curve is normal. //[ void pcm3070_setbass(unsigned char sr, unsigned char b)]
Set the Treble shelf gain from -3 to 0, it also ok, but when set 0 to 3, the SPL vs FREQ curve reduce. // [void pcm3070_settreble(unsigned char sr, unsigned char t)]
Then we use PCM3070EVM to set these and connect our power amplifier, All are normal.
Any other need to set to solve it when we use MCU to set the trebel gain ? Attachment for your reference.
we can send the pfw file and C file to you if need .

Hello TI,
I would like to know if any commercial counter part is available for ISL75051 from TI Non- Radiation hardened device. Same functionality and Pin out is preferred.

Part Number:CC1352P
Hi Sir,
I found one GitHub page and described developing and running Contiki-NG on TI SimpleLink™ devices.
But it say " Not tested with TSCH " , does that mean Contiki-NG not support TSCH in CC1352 now ?
