Dear,
I have a simple question for TPS65235-1 Vin Power Rail, which is supposed to be 5V, 12V and 15V. I've understood that most LNB receiver is working in 12V Vin power platform.
Here my question is if there is any special purpose to support 5V Vin in certain applications. Is it for USB Satellite Receiver Sticks? If then, is it good enough to supply required current through USB?
thanks for your information in advance.
Part Number:TMS570LC4357
Hello,
We have received thanks to alert notifications (in February 18, 2018), a mail indicating that several documentation were added for the TMS570LC4357 (user guide, application note, errata, datasheet, etc...).
In the TMS570LC537 WebSite it seems that all the documentation added is not addressed to the TMS570LC4357.
Could you confirm this is a mistake and the problem will be corrected ?
or
Could you identify clearly what documentation is addressed for the TMS570LC4357 ?
Best regards,
Christopher.
Part Number:BQ35100
Hi,
Now the customer start to consider bq35100 and learn about EOS algorithm. The are considering Li-SOCl2 battery so they understand that the EOS mode should be used. Then can they get accurate SOH value at EOS mode also? Please let me also the reason that the EOS mode is recommended for Li-SOCl2 battery.

Hello,
I want to output at 4.31 MHz through the gpio pin 3.
But when i was test output frequency, It's maximum frequency is 300KHz.
//
while(1)
{
write(ofd, "1", 1);
write(ofd, "0", 1);
}
//
I try to find another method, for example, mmap or kernel space.
But i don't know how to use...
What's method i to use and how to use to make up frequency.
Thank you.

Part Number:TPS2068
HI,
We are planning to Use TPS2068 for switching ON/OFF of 3.3V based on a 12V enable .
Please see the below circuit .
The input V3P3_BP need to be switched to output if the V12P0 is 0 at the Enable . When 12V is present the switch should be off and there should not be any reverse current / voltage that should come from the out to In .
also can i leave the OC pin floating
is this ckt ok for my applaication

Part Number:CDCE62002
Dear Team,
our customer would like to use the CDCE62002 as jitter cleaner for a high speed interface reference clock @ Artix 7 FPGA (some more specs, see below).
They have to reduce the jitter from 100ps rms down to 1ps rms.
>> Is the CDCE62002 a good option for those requirements, or can you recommend another solution?
Looking forward to your feedback.
Best Regards
Martin

Part Number:TRF7970A
Hello,
I have two questions for Errata Device#B08 of TRF7970A.
Questions are for the description of "Erroneous behavior which results in not receiving data in the FIFO."
1.In case the issue is caused after power up and FIFO cannot receive the data, is FIFO recovered from the illegal status after a while?
2.Do you have any guide which shows the wait time after power up to avoid the issue?

Part Number:66AK2G12
On behalf of customer:
Dear,
My customer now are thinking to use 66AK2G12 as DDR-less system.
Question:
When this condition, I think I should set Power Estimation Tool as “DDR3:State:Enable”, and “Utilization=0%”, Am I right?
In other words, I think I should not set DDR3:State:Disable even if DDR-less system, because there are some leak current. Am I right?
I really appreciate your advice.
Best regards,

Part Number:TDC1000-GASEVM
Good morning,
i have recently bought the TDC1000-GASEVM board because i have to evaluate the distance in air between two transducers (one transmitter and one receiver).
If i use the Boost board there are only two connections, both for the transducers (TX1 and TX2).
How can i physically connect the receiver?
Furthermore, i have to change settings in the setup mode?
Thank you!

Part Number:TMS320F28062
Hi,
I have a question about the absolute maximum rating of the F2806x's ADC input.
The absolute maximum rating of analog voltage of -0.3 to 4.6 V is prescribed in the data sheet,
is the input of ADC the same, too?

Part Number:CC2650
Hi,
I am trying to interface DS18B20 Temperature sensor with LAUNCHXL-CC2650, the sensor uses 1-wire library.
In 1-wire library same GPIO pin in the controller is used for both Input and Output of data.
I can not get a proper solution to get temperature from it.
I have tried implementing 1-wire library concept of arduino but it doesn't work.
Have anyone used 1-wire library on CC2650 or CC2640? If so please guide me.
Part Number:TMDSICE3359
I am use Processor SDK 4.1 and have the EtherCAT_Slave_01.00.05 application running on my ICE board. The LCD shows the name of the application that is ethercat slave demmo.
I am trying to connect my board to my PC which has the TWINCAT 3 software. I have followed the step mentioned in the quick start guide. However i am stuck at this point :
Go to I/O- configuration> I/O devices- Right click on scan devices
The scan devices option can not be selected.
I tried it with 2 different computers.
One having Windows XP on virtual machine with Realtek network adapter and the other having Windows7 -32 bit with Atheros Erhernet controller.
Facing the same problem with both of them.
Part Number:PMP10921
Tool/software: WEBENCH® Design Tools
Hello Gurus ,
I am trying to build a charger which could charge my Li-ion 5300mah battery with 2C charge rate.
I have currently selected 5V 10A SMPS as a adapter source.
The reference design PMP10921 is designed for 3 Cell series stack and being new to power electronics , I would like to know if 2C(~10A) charging would be feasible design with BQ24600 ?
If I use MSP430 instead of BQ24600 will my charge time reduce because we don't have charge time optimizer in MSP code.
Also as I am going to have huge quantity, could I get any TI members contact to discuss on costing and technical support for product.
Thanks a lot.

Dear Champs,
My customer is trying to run SV DEMO on TDA2 EVM using pre-built image included in VisionSDK v3.02 and successfully to run DEMO display, but there is only 1 camera displayed in SV DEMO. Could you please let me know settings of Vision daughter board and deserialize board to run SV DEMO?
in my customer's display,
camera1 and 3 - blank.
camera2 - green(only green color displayed)
camera4 - display
When I changed cameras each other, same situation occurred as above.(only camera4 was displayed and camera2 was green)
customer's SW3 of Vision board is as below.
and deserializer board is as below.
Thanks and Best Regards,

Part Number:OPA2189
hello,
I looked at figure 43b of the OPA2189 Datasheet and was wonder if the input impedance of the plus terminal should be matched to the input of the minus terminal.
I need to invert 1 PPM 5 volt signals and was wondering if the inputs should be matched to terminate biases or that it's better to have the plus terminal grounded.
Awaiting responses

Hey,
We've encountered a strange issue - when listing the files on the CC3200MOD FLASH, in one of our devices, there appeared an "arp" file which was unknown to us.
This file was not created by our FW and so it appears something in the simplelink library has created it.
The strangest part is that we have many units, using the exact same FW and servicepack, but in only one of them this file appears.
My questions are as follows:
1. what is the exact meaning of this "arp" file?
2. when is it created? how is it possible that some of the devices have it and other don't?
3. is there a way we can insure it will never be created? This is crucial for us since we have strict planning of the utilization of space on the FLASH
4. Are there any downsides to working without the "arp" file?
Thanks in advance,
Tal
Hello,
How to select the coupling capacitor in a sepic converter?
Also what is the effect when the coupling capacitor get short circuit? whether the output voltage will go down?
What will happen to secondary winding current?
Waiting for your reply.
